I got an RFE to provide documents of non-immigrant status and any employment authorization since last lawful admission into US.
The documents I gave them were :
Copies of I-797 (H1b approval notices with the bottom tear off portion containing the new I-94)
You need to also make copies of your I-94 attached to your passport both front and back, any status valid or expired.
Copies of EAD if any
Tax returns since the last lawful admission in my case 1998 thru 2001.
Copies of paystubs 1999, 2000, 2001 & 2002. I selected 3 for 1999, 2000 & 2001 randomly and gave the last three paystubs for 2002.
Have a home so property tax for last 2 years.
If you go thru the RFE doc it talks about document which include credit card statements, utility bills, rent receipts.
All they want to be sure is that you have maintained your status since you came into the country.
