I am going to file I-539, Application to Extend/Change Nonimmigrant Status for my mom. I read the instruction and prepared the following documents:
1. Filled Form I-539,
2. Check $290 payable to U.S. Department of Homeland Security,
3. Copy of her I-94,
4. Copy of her passport,
5. copy of my 2010 tax return and W-2 (in part 4, I explain that I will support her life for another 6 months.)
Are these document enough? If not, what else we need? Thank you very much!
