Moving to another state after getting GC

[k.ambrose]

Greetings,
I received my legal permanent resident status last December and do not have any pending cases at the moment. (I will need to send in the appropriate documents in 2009 for the 10-year card, but nothing else at this time). I have a couple of questions and would appreciate your thoughts.

I will be moving out of my current place to a neighbouring state at the end of this month. I will also be spending the summer back in my home country with my husband as we need to participate in our cultural wedding ceremonies. Once I come back from abroad, we will be moving in together to a yet unknown apartment. My question is when do I fill the AR-11 form?

I won't be able send the AR-11 before I move out of my current place,which was the address we used for the AOS process, because we do not have a future address yet. Is it possible to have a PO Box set up for any mails from USCIS while we're abroad and change the address within 10 days of moving into our new place in Aug? Any inputs would be appreciated. Thank you.

I don't think you can use a PO box with the USCIS. Someone will correct me.

you can use a PO box for a mailing address, but you cannot use it for AR-11, since you can't reside at a PO box.

Hello again k.ambrose! Do you have no plans to maintain a physical address at all? Which address will you be using for mail forwarding, bank statements, cell phone billing address etc. during summer? Where do you store your stuff? What will be your driver's license address? What address will you list on your US customs form upon re-entry? Address on file with the IRS for tax purposes? Registration and insurance address of your vehicles?

Here's what comes to mind ...
(1) keep an apartment while you're overseas (probably the most expensive option but has worked well for me ... I'd say it's worth it for ~1 month vacation but maybe not for example 3 months ... maybe sublease a room somewhere or find some roommates that will share the cost and use the space while you're gone?)
(2) change your address to a friend or husband's family (I think you wouldn't really be misrepresenting anything because you're not even in the country, you may as well claim to have your residence anywhere in the US that you choose while you're traveling.)
(3) put your mail on hold at the post office with your old address; I suppose your address could technically remain your old apartment address in the meantime. Certainly, for your new apartment you can't file a change of address until you live there.
