So I have received my physical green card. I foresee a trip of no more than 3 months out of the country to UK and Pakistan, starting May. But once I return in say in August, I am going to have to structure my life differently. I do foresee unavoidable frequent trips out of the country to UK and Pakistan - UK because I have some professional commitments as a barrister there and Pakistan primarily because of my elderly parent who is living alone there but also because my own neurosurgeon is based there and I do trust him most for follow ups on my brain tumor. Do you think it is a good idea to get a re-entry permit just in case (even though I don't see any trip beyond at most 4 months - or may be a total of 5 months in a single year broken down at two different times of a year)? I have gotten conflicting information on this, so following are my questions, if you would show the usual kindness and answer them:
1. Can you come and go during the period of the re-entry permit or is it a single entry kind of thing?
2. How long are re-entry permits valid for?
3. How long does it take for re-entry permits to be issued and is it possible to have it delivered at the Embassy/Consulate in Pakistan?
4. I understand that the longest you can stay out of the country is 2 years? Is that correct?
5. How many times can a re-entry permit be renewed?
In short is the re-entry permit worth it?
Just so that you know my ties with the US are that my spouse and both my daughters would be living here. Are there any other ties I should establish.
I thank you as usual for your consideration and kindness.
