[sbreddy]

Hi Immigration Gurus,

I know many people are very busy with I-485 filing. I'm also in a process of filling these forms but stuck with few questions...I would appreciate if anyone helps me in this....

1) what is
File Number A:
Alien registration Number:
Immigration file number:
Non immigrant VISA number:
are they all same? .

2) My L1 VISA in 2002 issued in Chennai, INDIA
L1 VISA in 2003 issued in USA,
From I-485 form under Part3. Processing Information, What I suppose to use when there is a question,'counslate Where Visa Was Issued'?

3) what is the 'class of admission' from I-131 form, under the section Part1 Information About You.?

4) My wife is on H1 and working but applying GC through me, what are the forms I need to fill for her along with me like advance parole etc...?

Thanks in advance...

Reddy
