Does anyone know M1 visa?

Sorry..I can't find anything.
If she come back home,does it mean her M1 visa will be expired?
She still has F1 visa in her passport.Is it still valid before she go to the U.S. again?or she needs to apply it and go to US embassy again?
Thank you.

** Please go back to this earlier thread you participated in and refer to the links about M1 and F1 visa:

What exactly is your friend taking up? Associate degree in nursing? When is she graduating? Actually, even if she is on an F1 visa and will be graduating soon, she needs to be in either OPT or continue to be a student to be able to stay if she wants to wait for a window to adjust status if she can't do any of those 2 things, she needs to leave US within 30 days after graduation. Some are just upgrading from ADN to BSN or from BSN to MSN just to be able to keep staying in the US. She needs to consult her International Student Adviser if she wants to maintain to be a student. But there is no guarantee that that window will even open.

How about M1 to GC via unskilled worker?
