My mom was here on B2 visitors visa, her I-94 was getting expired on Jan 16th. I applied for I-94 extension, but she had to leave US before her extension was approved because of health reasons. She left on feb 5th.
Now the USCIS website case status says the extension is approved and notice sent. I am yet to get the approval notice
My question is,
1. Should I return back the extended I-94? If yes to where? Any procedure to be followed so that she doesn't end up in any problem if she has to return back to US.
2. Any documents she needs to keep which will proove that she didn't stay for the period extended.
3. What documents she need to bring when she is coming back to US (may be in Dec 2008), to convince immigration officer that she didn't stay too long?
Thanks for your time
