I am a guy from Nepal residing in United States currently in F1 visa .
Right now i am in OPT ( Optional Practical Training ). My OPT expires on Jan 17,2010.. I am totally unaware of my status of immigration rule if i marry a permanent resident girl. I would be very pleased if anybody could help me out answering my queries?

1. I am planning to marry a permanent resident girl who is here in US from the past 2 years.
After getting married what will be my status? I have gone through the
website of USCIS and found that she need to file a form I-130 on my
behalf. What will be my status after she file I-130? How long does
USCIS ( United States Citizenship and Immigration) take to change my
status? If not that what do i have to do to be in status?

2. Can i stay legally in US after she file I-130 till the decision is pending from USCIS about my status? How much time will they take ?

3. What will be my status if they approved the application?Will  i get a work permit if
they change my status? If yes How long does it take for the process of getting
work permit after the date of application?

4. Right now I am a student on OPT (
Optional Practical Training). I have a work permit it expires on Jan 17 2010.
What will be my Status after Jan 17, 2010 after getting married with the girl?

I would be very pleased if you could give the answer.

Thanking you in advance
