Dastiyasha@yandex.com, Hi what Ms have you completed ? Do you know any good Ms Microbiology university with possibility of getting PhD offer in future?
Dastiyasha@yandex.com, Please look int below link, hope it clarifies. https://www.uscis.gov/visit-united-states/extend-your-stay I think you can extend your stay while you are in US itself.
Dastiyasha@yandex.com, Hey, you are good as long as you have valid i-20 you don’t need visa but let’s say your visa expired before you complete your PhD than too you are good a long as valid i-20 and you are in USA but if you leave USA than you can go to consulate and have them show your valid i-20 they will stamp you new visa on your passport but if you don’t leave USA than you are all set.
Rathodshweta, Thanks Guys, So if I need to go someplace out if the US after my visa expires then i'll have to go to the indian consulate here in the US and just get a new stamping or will I have to give an interview again?
