sorry la,
last time she already became illegal over stay . she can not go to USA again for at least 10 years.
not matter what happen or exception. even her son tomorrow become US citizen she still needed to wait for that 10 years period.
agree. stay over the period --
within 6 months, will not allow to re-entry US within 3 years
over 6 months, will not allow to re-entry US witnin 10 years.
I don't think that she will get a chance to go to US within 10 years from the time she returns to hk.
