F Visa

I was approved for my OPT on February 2008 for a duration of one year. At that time, I was allowed to stay in US for 1 year while looking for job. On April, 2008, a new regulation came according to which a student on OPT can not stay in US without job for more than 90 days. I was not aware of this rule until end of September 2008. Now I have applied for dependent visa. My worry is that unknowingly I stayed for around 6 month without job when I was actually allowed for only three month.

I am worried that is this mistake going to affect my new visa approval? Is there anyway I can explain USCIS that it happened because I was not informed about this rule and I did not come across it.

After a long-term relationship, earlier this year I married a U.S. citizen. I do not want to change my immigration status and do not wish to immigrate nor reside permanently in the United States since we both have steady jobs outside the U.S. and I do not want to leave my country. All I want is to be able to travel temporarily into the U.S. for pleasure and leisure as most tourists do, once or twice a year for a couple of weeks each time.

I want to know if I can just apply for a new B-1/B-2 tourist visa to travel into the U.S. or if my husband needs to file an I-130 petition for alien relative and I-129 and K visa thereafter instead –which I understand would be the right process if I ever wanted to adjust status or become a U.S. permanent resident.

I have a tourist visa to the US which expires in 2009. However, back in 2004, i was able to obtain a F-1 visa for MBA studies. It expired in 2006 and my stay was extended through practical training. I have all necessary documents supporting that. My question is, will I still be able to use my tourist visa until the March 2009 expiration?
