B Visa

I have done my masters in USA and stayed there for 4 years and came back to India. My visa got over on Jan 2013, and I plan to pursue my MBA in USA and went for the visa interview twice it got rejected, and now my friends and family are suggesting me to apply for B-2 visa. What should I do?

As my husband's H-1 expires, we are moving back to India around August/September. I am exploring options to quit my job (also on H1) in the last 2-3 months, but since this is a short period, I'm looking for the most convenient and economical transition. Can you please advise:
- Convert to H4: What is the expense incurred and how much in advance would I have to apply for this?
- I have a tourist visa that is valid till 2016- can I take advantage of this?
- Is there a grace period after leaving a job here (giving up your H1) that I can take advantage of if I time it properly?

For a CBP port of entry, what is the procedure available to seek supervisory review of an officer’s refusal to admit a visitor due to the period of time he or she was previously present in the U.S.?

I recently abandoned the US for Canada. I had been living in the US illegally for 15 years (since the age of 11). I got an opportunity to conduct biological research at the University of Alberta, AB, and Canada. I'm fully funded to live in Canada by the institution. Anyway, I would like to return to the US in 2013 for my 10 year high school reunion. I would like to know how likely I would be to get a tourist visa given my recent history. I have no intentions of staying in the US, just visiting. Am I automatically banned?

I am having a problem getting my visitor visa. My fiancé is a US citizen and my sister is on H-1B visa she is there since 3 years with her family... my parents got their (B1-B2) visitor visa. But when ever I apply for B1-B2 I get rejected. My question is, when they ask me why you want to go to the USA my answer was to visit my sister and her family. Now can I answer like this? My fiancé is a US citizen and I want to meet her and get married.

Will I get 15 days visa for US as tourist visa and in this time marry a friend who is U.S citizen and also born over there in USA, so could I be able to apply for visa extension and then apply for PR in USA?

I am a US citizen - my partner is a citizen of the UK (we are not married). He is a consultant in the international development field so travels frequently, but often visits me in the US when he is not working. He has been to the US for visits of 2-3 weeks duration about 6 times in the last year. The past few times, immigration has hassled him about the number of visits he is making. We are concerned that one of these times he may be refused entry - is this likely?
