I am completing my bachleor degree in computer science in december 2009.
I never go back to my country because I have not multiple f1 visa, friends and my school counso=lor told me that I have to go back to my country and get multiple visa from the embassy. But again it is risk? They might be reject!!

My family went home land USA embassy for an interview and visa officer rejected 2 time F2 visa, Visa officer said that I came on visitor visa and changed my status in to F1 and still staying USA. so, they afraid my family will do same thing.

a. Yes, on H4 visa.
b. Possible. But you still run the risk. H1 is dual intent, but you violated the terms of visas issued to you severly in the past, so the consulate may consider that in their decision.
c. You can, but it'll be difficult to get it, same as for F2.
