i am a resident since 1983 i just came from canada from a 4 month trip and i will be in U.S. for 30 days
---------- that is ok if your trip was for 4 months.
if i go back does the last 4 months add to the 4 months i will be out for ??????
------------ NO, it will be your next visit and dont stay more than 6 months
and if you say my best bet is a re entry permit ( I-131) can i leave 3 weeks after i send it and wait for answer from canada .
------------ you need to apply Rentry Permit while you are in US, the day your Reentry application reaches USCIS you can go out you can give your US address to send Reentry permit or you can give US consulate in Canada to pick up the reentry permit
i married her in the last trip,i also now want to take out my citizneship and i was wondering if the ( I-131 ) will affect my citizenship, does it make any difference that i have bin in the US as a resident since 1983 she will not move to the US cause she has to finish her studies and i hear to take out my US citizneship i have to be in the US.
---------------- your question is not clear, if you are GC holder since 1983 why not to apply US citizenship?? apply for US citizenship and it may get approved in 3-5 months and after that file for her. you did not provide facts of your case did you stay out side US in any trip more than 6 months in past? did you pay your US tax in past?
it should not be so hard for me to be happy with her and do the right thing.
thanks
