Do I need to inform of change of address?

[Orela]

What is the name of your state? California

1. I am a permanent US resident (unconditional green card) and we will be living in Europe soon for a year, or longer. We will keep our PO Box though. Do I still need to inform immigration within 10 days once we have our residence address in Europe, or is our PO Box fine now that I am a permanent resident? As, we will keep our PO Box and might come back in approx. 1 year, or so.

2. Can I still apply for dual US citizenship, even though we are currently not living in the US (my spouse is a US citizen)?

Any advice, and info would be greatly appreciated? Thanks in advance!
Have a great day!

Sincerely,
OrelaWhat is the name of your state?

1. YOu DO need to inform the USCIS of any address changes. Furthermore, as a LPR, you cannot just LIVE in Europe for an extended period of time and not lose your LPR status so I would strongly advise you to apply for a reentry permit before you go to Europe for a year or longer
2. As for applying for US citizenship, you can only do so if you have been a LPR for the requisite period of time and if you otherwise qualify for naturalization. You have to be in the US in order to apply.

Please let me know if you have any additional questions or how I can be of further assistance to you in this matter.

"2. As for applying for US citizenship, you can only do so if you have been a LPR for the requisite period of time and if you otherwise qualify for naturalization. You have to be in the US in order to apply."

Depending on the nature of your USC spouse's relocation abroad.. if military, you may qualify for expedited naturalization.
You should download and review the Guide to Naturalization to look at the continuous residence rules and see how long you need to be back in the US before you file (District rules).

Definitely apply for a re-entry permit before you leave. It is valid for an absense of 12-24 months.

See uscis.gov "Now That You Are a Permanent Resident" for the list of other things you must do to preserve your residence.

You can also investigate a Returning Resident's visa (SB-1) or re-immigrating through your spouse when you are ready to return to the US to live permanently.

Your husband may not be aware that as a US citizen, he must report his worldwide income, so he will need to file a US tax return even if he does not owe money due to tax treaties.
