My mom has 10 yr MUL. She came here in first week of February so that her 6 month stay would cover my son's first birthday and has got a return ticket for August first week. But on her arrival at Newark Airport, she could not mention that and she got a stamp for 3 months.
Now I need to file for an extension but I would prefer to not to wait till last minute and not to live with that unknown. So please advise on following...
1) Do you think that now giving the honest reason, 'to participate in grandson's first birthday' would be good enough? Even though she should have mentioned the same at the time of arrival and could not!
2) How soon can I and shall I file for extension?
3) As form I-539 indicates, shall I send original I-94 along with application or should I send a copy only as mentioned on immihelp.com
Any advise in the matter would be greatly appreciated.
Thanks in advance...
