Anyone asking “who is eligible for the draft” in the U.S. is basically asking who must register with Selective Service, and who could be called if Congress ever restarted conscription.

Quick Scoop: Core Rules

  • Who must register (today): Almost all male U.S. citizens and male immigrants ages 18–25 must register with the Selective Service System.
  • Citizens abroad: Male U.S. citizens must register even if they live outside the U.S. between 18 and 25.
  • Immigrants: This includes naturalized citizens, permanent residents (green cards), refugees, asylum seekers, undocumented immigrants, and most others once they’re living in the U.S. between 18 and 25.
  • What registration means: Registration just puts you in a database; no one has been actually drafted since 1973, and a new draft would require Congress and the president to act.
  • Automatic registration is coming: Under the 2026 defense law, the government will begin automatically registering eligible males using federal data starting December 18, 2026, instead of relying on them to sign up themselves.

In other words, “eligible for the draft” in practice means “in the pool because you were required to register between 18 and 25.”

Who Is Required to Register (and Would Be Draft-Eligible)

As of now, these people are required to register and would be in the pool if a draft returned:

  • Male U.S. citizens ages 18–25 (including those abroad).
  • Male immigrants in the U.S. ages 18–25, including:
    • Naturalized citizens and permanent residents.
* Refugees, asylees, parolees.

* Undocumented immigrants.

* Those whose temporary visas have expired more than 30 days ago.
  • Dual nationals (U.S. and another country), even if they live outside the U.S.
  • Men with disabilities, even if their condition would likely make them unfit for actual service; fitness is evaluated later if a draft happens.
  • Men in the existing Armed Forces still have to register separately in many cases (the system’s own guidance covers specific categories).

If a draft were activated, the government would run a lottery based on birth year and date, then call people up in that order and test them for physical, mental, and moral fitness.

Who Generally Is Not Required To Register

Some individuals are not required to register at all, or would currently be outside the registration age window.

  • Under 18 or older than 25 (for registration purposes; historically, draft calls have focused on 18–25, sometimes a bit older in wartime).
  • People on valid non‑immigrant visas (for example, certain students or tourists) who stay in valid status until at least age 26.
  • Women and girls: current law requires only males to register, although there have been debates about including women.
  • Some narrow categories under federal rules (for example, certain diplomatic personnel or specific foreign officials) are exempt from registration.

Even among those who are registered, there are deferments and exemptions that could apply if a draft were actually activated (for example, severe medical issues or qualifying conscientious objection), but those are decided only once a draft exists.

How a Draft Would Actually Work

If Congress and the president restarted conscription, it wouldn’t pull “everyone” all at once.

  1. Lottery: Birthdates for a given year of birth are drawn in random order in a public lottery.
  1. Call‑up sequence: Men in the required age group are called in the order of their lottery number and year of birth.
  1. Screening: Each person is examined for physical, mental, and moral fitness; some are deferred, exempted, or disqualified, others are inducted.

A simple illustration: a 19‑year‑old male citizen and a 22‑year‑old male undocumented immigrant both must register and would both be in the pool; a 30‑year‑old woman or a 27‑year‑old man generally would not be.

Forum / “Trending Topic” Angle

Online discussions in 2025–2026 often mix up two things: the legal requirement to register versus the political question of whether a draft will ever actually come back.

  • Many posters focus on fairness questions: why only men, whether women should have to register, and what should happen with dual citizens or immigrants.
  • Others worry about penalties: not registering can affect eligibility for some federal jobs, student aid, and in some cases naturalization for immigrants.
  • There is also new attention on the 2026 change to automatic registration from government databases, which some see as a bureaucratic fix and others see as “quietly tightening” draft readiness.

A common forum line is: “We don’t have a draft now, but if they ever bring it back, everyone who had to register between 18 and 25 is the first in line.”
