Joining the Peace Corps is not like taking a typical job offer. An applicant who is conditionally invited to serve still has to clear two separate reviews before departure, a legal clearance built around a background investigation, and a medical and dental clearance built around a full health history. Both are run directly by the agency, not by an outside consumer reporting company, because Peace Corps Volunteers are not employees in the ordinary sense. They are enrolled under the Peace Corps Act after taking an oath of service, and the rules for who can serve come from federal regulation rather than from an employer’s own hiring policy.
This guide walks through what the legal and medical clearance process actually covers, how past arrests and convictions are evaluated, what host country and intelligence related limits apply, and how the screening of Peace Corps staff differs from the screening of volunteers.
Legal clearance and the background investigation
Under the Peace Corps Act, the agency must investigate every applicant to confirm that enrolling the person as a Volunteer is consistent with the national interest. The Peace Corps explains this directly on its legal clearance page: applicants must fully disclose their legal history, including any citation, arrest, or charge, regardless of whether it was dismissed, sealed, reduced, or expunged. Most of the legal clearance work happens after a conditional invitation, when the applicant submits fingerprints and a background investigation certification form. An applicant cannot depart for service until legal clearance is granted, and the agency warns that failing to disclose an incident, even a minor one, can lead to a rescinded invitation on nondisclosure alone, separate from whatever the underlying incident was.
The regulation behind this process sits at 22 CFR Part 305, Eligibility and Standards for Peace Corps Volunteer Service. Section 305.8 of that part states that the Peace Corps obtains an appropriate background investigation for every applicant invited to serve, and that if the investigation turns up data suggesting an applicant is of questionable loyalty or a questionable security risk, the matter must be referred to the Federal Bureau of Investigation for a full field investigation, with the results returned to the Peace Corps for action. This is the mechanism by which an FBI level check can enter the process, though it is reserved for cases that raise a loyalty or security concern rather than applied as a routine step for every applicant.
How past arrests and convictions are evaluated
The Peace Corps does not automatically disqualify someone because of an arrest or conviction record. Under 22 CFR 305.5, the agency considers the nature of the offense, how long ago it occurred, whether the applicant was acquitted, the terms of any parole or probation, and other evidence of rehabilitation before making a decision. The agency’s own eligibility and core expectations page repeats this standard in plain language, and both the regulation and the agency page note that an applicant who is rejected because of a past arrest or conviction can request a review of the decision or reapply later.
Drug and alcohol related offenses are handled with a specific, fixed rule rather than a case by case judgment. Under the same regulation, an applicant with a drug related conviction, or a conviction for public intoxication, driving under the influence, driving while intoxicated, or a similar alcohol related offense, is not eligible to have an application considered until 12 months have passed from the date of the incident. An arrest for any of those offenses at any point up to the day of departure results in a withdrawn application or invitation. If the charge is later dismissed, the applicant may reapply immediately. If convicted, the 12 month waiting period applies from the date of the incident. Separately, the Peace Corps maintains a zero tolerance policy toward drug involvement during service itself, and Volunteers and trainees are required to sign a drug free service agreement as a condition of continuing consideration.
Medical and dental clearance
Medical clearance is a distinct process from legal clearance, run by Peace Corps medical staff rather than the legal eligibility office. According to the agency’s medical clearance page, every invitee completes a Health History Form and is assigned a pre service nurse who reviews the applicant’s medical history, immunizations, current conditions, and ongoing treatments. Cases that need a closer look may also involve a physician or a behavioral health professional. The review is individualized, so the number of required exams, labs, and specialist evaluations varies by applicant, country of invitation, and assignment. Required medical, dental, and mental health exams and related diagnostic testing are reimbursed by the agency, and the Peace Corps states plainly that failing to disclose medical information during this process can be grounds for removal from service later.
Medical clearance decisions are tied to what care is realistically available in the country and post where the applicant would serve, not to a single national health standard. The agency may determine it cannot support a particular condition in one country but can support the same applicant in a different assignment, in which case it may offer a different country rather than simply denying clearance. This country specific framework is also reflected in 22 CFR 305.4, the medical status eligibility standard within the same eligibility and standards regulation.
Host country and other limiting factors
Because Volunteers serve inside another country’s communities and often work alongside host government partners, a few categories of applicant face automatic or extended limits that have nothing to do with a criminal record. The eligibility page explains that anyone who has been employed by the Central Intelligence Agency, including as a contractor or intern, is indefinitely disqualified from service. Anyone currently or formerly employed by another intelligence agency is ineligible for at least 10 years from their last date of employment, and even an intelligence connection through a family member rather than the applicant’s own employment can be a disqualifying factor, evaluated case by case. These limits exist, in the agency’s words, to protect the trust that host country partners place in Volunteers who have no connection to intelligence work.
Citizenship rules are separate again. An applicant must be a U.S. citizen, established by birth or naturalization, and every invitee must obtain a no fee U.S. passport for service. The United States does not recognize dual citizenship for this purpose, so an applicant who holds a second citizenship must still apply for the no fee U.S. passport and may face additional considerations if being considered for service in the country of that other citizenship. An applicant whose citizenship is still pending naturalization can apply, but cannot be conditionally invited until after taking the Oath of Allegiance.
| Review | Who runs it | What it mainly covers |
|---|---|---|
| Legal clearance | Peace Corps Office of Legal Eligibility | Fingerprint based background investigation, full disclosure of arrests and convictions, citizenship and intelligence connection review |
| Medical and dental clearance | Peace Corps pre service nurses, physicians, and behavioral health staff | Health History Form review, required exams and labs, fitness to serve in the specific country and assignment |
| Staff suitability (federal employees) | Agency human resources, under OPM suitability policy | Background investigation tied to the position’s federal employment risk designation, not the volunteer legal clearance process |
How staff screening differs from volunteer screening
Peace Corps Volunteers are not federal employees. They take an oath and enroll under Section 5 of the Peace Corps Act, and their eligibility is governed by 22 CFR Part 305, the legal clearance and medical clearance process described above. Peace Corps staff, including the agency’s domestic headquarters employees and overseas staff who hold federal positions, are federal employees, and their background screening instead follows the government wide suitability and fitness framework that applies across federal agencies. That framework, set out at 5 CFR Part 731, requires a background investigation whose scope depends on the position’s designated risk and sensitivity level, with the Office of Personnel Management serving as the suitability and credentialing policy lead described on its own suitability program page. In short, a volunteer’s screening is a program specific legal and medical review built for people being sent to live and work in another country, while a staff member’s screening is the same kind of federal suitability investigation used across most other civilian agencies.
What applicants should expect to disclose
The clearance process depends on complete and accurate disclosure at every stage, not just at the initial application. The legal clearance page is explicit that incidents the applicant leaves off the paperwork will still surface in the background investigation, and that the nondisclosure itself, not necessarily the underlying incident, can be the reason an invitation is withdrawn. The same principle applies on the medical side, where failing to report a condition or treatment history can lead to removal from service after departure rather than a straightforward denial during clearance. Applicants who have a new legal issue arise after a conditional invitation are instructed to contact the Office of Legal Eligibility directly rather than wait for the background investigation to catch up with the new information.
Frequently asked questions
Does the Peace Corps run an FBI background check on every applicant?
Every applicant who receives a conditional invitation goes through a background investigation, which includes submitting fingerprints. Under 22 CFR 305.8, a full field investigation by the Federal Bureau of Investigation is required specifically when the background investigation raises a question about an applicant’s loyalty or security risk, rather than as a routine step applied to every invitee.
Can someone with a past arrest or conviction still join the Peace Corps?
An arrest or conviction record does not automatically disqualify an applicant. The Peace Corps considers the nature and timing of the offense and evidence of rehabilitation under 22 CFR 305.5. Drug and alcohol related convictions carry a fixed 12 month waiting period from the date of the incident before the application can be considered, and an applicant rejected for a record can request a review or reapply later.
What does Peace Corps medical clearance actually involve?
After a conditional invitation, applicants complete a Health History Form and are assigned a pre service nurse who reviews their medical history, immunizations, and current conditions. Depending on the case, a physician or behavioral health professional may also be involved. The required exams and labs vary by person and by the medical resources available in the specific country and assignment, and required exams are reimbursed by the agency.
Why might an intelligence background disqualify someone from service?
The Peace Corps limits applicants with intelligence connections to protect the trust it builds with host country governments and communities. Former employment at the Central Intelligence Agency, including as a contractor or intern, results in indefinite disqualification. Employment at other intelligence agencies carries at least a 10 year ineligibility period from the last date of that employment, and even a family connection to intelligence work can be a factor the agency considers.
Do Peace Corps staff go through the same background check as volunteers?
No. Volunteers are screened under the legal and medical clearance process in 22 CFR Part 305, which is specific to Peace Corps Volunteer service. Staff who hold federal employee positions are instead screened under the government wide suitability and fitness framework at 5 CFR Part 731, administered according to Office of Personnel Management policy, with the scope of the investigation tied to the position’s designated risk level.
What happens if an applicant does not disclose something during clearance?
The Peace Corps treats nondisclosure itself as a potential problem, separate from the underlying incident. The agency states that unreported arrests, charges, or health conditions will generally surface later during the background investigation or medical review, and that failing to disclose can be grounds for a withdrawn invitation or, after departure, removal from service.
