Grandmother permanent resident status valid???

[Rim.K.]

Hi,
My grandmother came to the U.S. and resided here for almost 3 months but then went back abroad to see her family almost 5months ago. She is planning to come back to the U.S. soon. How long do you think she has to come back so long as it doesn't create a problem for her? I have been told 6 months is the max, but just would like any helpful feedback. Thanks in advance.

Under 6 months should be no problem. Between 6 months and 1 year is also fine; she might be asked some questions about how she has maintained residence. Over 1 year is not good, although they could still let her in if they choose.
