I am currently on H-1B visa. Is there a way I can change the visa to F-2 without going back to India? My fiancé is here on F-1 visa and this visa is valid till Sep 2014.
You must be married to the F-1 holder in order to be eligible for F-2 status. Fiances do not qualify for derivative status.
I have two more years to complete a Ph.D. with a valid I-20, but my Visa expires in August 2013. I want to visit India in June-July 2013. If I come back in July, do I need to apply for F-1 visa (and F-2 visa for my family) extension? Would I have problem in reentry if I have one more month of valid F-1/F-2 visa?
You will need a new visa only if you return after August 2013. Check with your DSO to make sure you have all the appropriate requirements completed.
I am on F-2 visa and it is valid up to 1 July 2012. My wife already filed H-1B in Apr 1st week.I am also planning to file my H-1B. So can I directly apply H-1B or fist apply H-4 and then after apply H-1B. How will it work?
If you are subject to H-1 quota, to get status within USA, you must maintain status till September 30. So, it appears you may have to apply for H-4 as well as H-1. Your lawyers can help you figure out the timing. Applying for H-4 now should not be an issue. But move quickly. You can file for H-4 online. Fairly easy.
