My mom came to US on Sep 21,2019 on Tourist Visa and her stay period is valid March 20,2019 and we booked return ticket to March 13,2019. I have applied for her extension of stay by submitting form I-539 on January 25,2019. I submitted the reason for stay as she wants to visit more tourist places. Thinking that form will be approved I postponed her visit to 3 months from March 20,2019 i.e we postponed her return ticket to India is Jun 20,2019.
On April 30,2019 I got an RFE asking for my last 3 months bank statements, my mom’s foreign residence proof, arrangements made for her departure to U.S etc. I want to attach the RFE document. How to do it?
What all documents I need to submit for the RFE? My question is if I don’t submit the RFE, how long she can stay in U.S?
