I just received RFE. Without old paystub, what can I do other than providing the legal paperwork(OPT, H-1B, etc)?
Submit a complete listing of all employment you have accepted in the US since your last admission.
The list must provide the name and address of the employer, the position you held at the
company and the actual dates(month, day, year) that the employment began and ended.
Submit evidence such as pay stubs which supports your claimed periods of employment at each company. The evidence
should cover, at least, the beginning and ending periods of your employment.
Respectfully,
