gooner.. you heard right. they are taking international personnels with F1 or H1B status i.e. non immigrant aliens. They are taking 1000 individuals from new-york and LA as of right now as this is a pilot program. If this program is to success they will be recruiting more in future. Recruiting from LA and NY doesnt mean that they are taking ppl living there only, if you can travel to LA or NY then you are good to go. Anyone can apply i dont think there is an age limit because when i was there, there were a whole bunch of indians who looked like they were in their 40's.
They take a series of test like medical, physical, ASVAB(written) test and a langauge test.( to check to see if your understanding of the langauge probably will b hindi).

Syanjali., i didnt quite get what you are trying to say but once you get in the army your citizenship will be provided within 6 months. they will train you and everything.

if anyone needs further info, you can always email me thru sajha. i would love to help.
