You can substitute any other country for Canada. The bottom line is you’re risking her green card. Yes people have been gone for five years and gotten back into the USA without a word from immigration etc, however not being discovered doesn’t mean it was acceptable. All it takes is one zealous observant immigration officer and she could be in trouble depending on the pattern and lengths of travel. There is no cast in iron determination aside for the 6 months and 12 months rules as already pointed out. Remember the idea is you get a green card to make your principal dwelling place in the USA.
 
My advice is err on the side of caution when dealing with immigration. 
 
Enjoy!

I'm American and she moved here from Ukraine.
 
The idea was to temporarily spend time aka 'live' there, while still keeping my house & health insurance here in the US, with a plan to return to the US full time after a couple years. Living up north is just something we've both been interested in as a temporary thing (kinda like how some people have the travel bug).
 
Thank you for that USCIS link. Sounds like absences from the US for less than 6 months are allowed, but with multiple of these, an officer can reject a naturalization application. To me it sounds like it could be safe if we were to spend 5 months in Canada one year, then again the following year, and then if we had 3 full years in the US before applying for naturalization, there wouldn't be much concern of whether or not we reside in the US (quote from the USCIS link that we need to be mindful of: "In some of these cases, an applicant may not be able to establish that his or her principal actual dwelling place is in the United States or establish residence within the United States for the statutorily required period of time.")
 
As I'm at the beginning of pursuing this idea, I haven't looked into all the details of doing this from the Canadian side, but I did read it can be fairly easy if a resident of the US has a remote job (sure, with some additional tax headaches), so I thought I'd look into what it means for the US immigration process first, which is the most important part for us.

Does anyone have experience of temporarily moving out of the US after getting their green card? My wife has an interview scheduled for the AOS (via K1 visa) soon, and we've debated living in Canada while working remote US jobs. Or maybe even spend most of the year in Canada, with a a few trips to the US. I'm trying to figure out what options are safe vs having the potential to cause issues for returning to the US if decided to live here in the end.
 
https://help.cbp.gov/s/article/Article-820?language=en_US this says a PR can leave as long as it's not for over a year. I take that to say that if we return the to the US every year (most likely 2-4 visits a year), there shouldn't be a problem.
 
Does anyone have experience or advice on if my take on this is accurate, or about other info I may be missing?
Thank you.

Look at it this way:  If folks intending to work prior to authorization were to disclose this to the CBP @ POE, do you think they would be admitted?

Here is the link for unauthorized work and adjustment of status. This is where you should get all your information Policy manual
I am afraid I can’t comment on something that is unauthorized. Your best bet is to study the policy manual that I just linked, and make a decision. I personally wouldn’t risk it.

You can search for people's experience on the forums specific to your embassy, or try calling or emailing the embassy.

Anyone know any members/threads who HAVE worked remotely in the US while waiting for the greencard? If someone does work remotely for a foreign company, is there any way for USCIS to know (I'm not debating ethics with this question, just asking if in some part of the process they can figure out that you did something you're not supposed to do).
 
After reading through some threads, I'm trying to straighten out my information. Is the following accurate:
1) It is possible to apply for an EAD (temporary work permit) while on the K1 visa, ie while being a fiance.
2) It is not possible to have an EAD after getting married (ie "nullifying" the K1 status) and waiting for the greencard.
2a) I thought a while ago I had read that when you apply for the greencard (let's say estimated 13 months to receive it, even though there is plenty of variability) you can also apply for an EAD, which could take about 5 months to get, but would allow you to work earlier than getting the greencard. Is this possible?

Thank you for the tip!! The non immigration side number put me on hold (vs the immigration number just told me to try again), and I got through to someone and got my case number.
Case was created 3 weeks ago, still being held at NVC, waiting for the consulate to be ready.

Call the non immigration side of NVC (603) 334-0888, you get through a little quicker and they should give your case number now it’s been over 6 week so they should have it, I’m right at 4 weeks so i will probably get mine next week…. More than likely beneficiary will get notifications by email
