Overstay on multile entry visitor visa

[jsikander]

My mother has a 10year multiple entry and was given a 6 mo stay when she came last year. We wanted her to stay more, filed for the extension in time and got the reciept notice. She overstayed by a 35 days and left before the response for the extension came. INS responded after she left that they needed some further documentation (interestingly the additional documentation they were looking for was already attached with my request), I did not respond as my mother had already left.

Now my mother plans to visit us again in few weeks, would she face any problem, do I need to send any documentation of support etc, she has the reciept notice of the extension that was filed with her.

Thanks.
