- You can get naturalized. https://www.uscis.gov/military/naturalization-through-milita...
- It's the U.S. Military, so pretty good record on the whole. Maybe if you look the other way on Vietnam, Abu Ghraib, Blackwater, misbehaved politicians and their silly e-mail servers, and the fact that it can kind of be ugly business.
- Free college, if you have kids you can confer it to them.
- It's a job, dollar-amount-wise pay won't be competitive, but it's non-zero, and yields non-cash benefits such as the VA loan, aforementioned GI bill, and a litany of other benefits from both state and federal government. https://www.va.gov/opa/publications/benefits_book/2020_Feder...
- May be able to select your own job, and get a standard technical career education in that trade.
- Sense of duty, discipline, world-class paralegal-type education/MBA-type organizational-business operations exposure, physical-health-type education and training. (MBAs aren't too popular around here, but the frustrating language they use to discuss things is pervasive and hence useful). In all likelihood, you'll skip away with a lot of soft-skills, a stronger body, a wallet, a retirement fund, and a diverse set of friends. As the Military is bound to law, every action must be assessed in terms of law, and all activities are governed by law. Well-meaning contributors over hundreds of years have written law, orders, doctrine, policy, manual, and regulation often in blood, you get to pick that all up.
- Huge community of invested contributors, VFW/American Legion admission, common ground with many Americans as the DoD is the world's largest employer.
- There's options to potentially serve locally such as Guard or Reserve, you might reach out to local recruiters from different branches to find out if that's an option.
You can check out the service-sites for more details, or maybe walk in to a recruiter's station and see if they're like, there.
