EO military?

Would you be able to joint he military with this new EO?

No. You need at least a Green Card to join any military

there is a possible exception...

what would be the exception?

It's not an executive order by the way, it's just a change in policy.

The Secretaries of Army, Navy, and Air Force, and Commandant of the Coast Guard could come in and allow individuals with the special EAD to join if they desire.

The program is currently on hold but if you're a EAD holder or some other form of legal papers besides a student or tourist visa and you have certain job skills that the Army would need you can be eligible to join the Army. It's called the MAVNI program. It's mostly for professionals and native speakers of certain languages. Basically they need more doctors, nurses and translators. It's a really good deal cause you get your citizenship in a matter of months and you skip being a green card holder.

I got a call from Fort Knox a few years ago to be a possible translator but my EAD expired already. If you think they have some skills that you would need i suggest for you guys to sign up. They take forever to respond but it can possibly be a good Plan B. Medical professionals don't like going into the Military cause they don't get paid as much haha.

^The MAVNI program expired some years ago but could the Department of Defense implement this via EAD alone definitely,Currently no!!!!

So is there or will there be an option to join the military after this EO?
