US Immigration from Canada

Has anyone mailed documents recently to the Montreal Consulate's US mailing address:

PO Box 847

Champlain, NY 12919-0847

Just want to confirm that it's still valid as I don't see it consistently listed in their contact us info.

Hi guys,

I am Canadian and am looking to file my taxes this year. I noticed that married filing jointly will be very expensive for me and my husband. We owe a lot of money that way. Our accountant advised us saying that we can file married but separately and that I (the beneficiary) don t need to file a tax return since I m a resident of Canada and can use the treaty to claim non residency in the united states.

The issue is I have been here since March and to me ... I d be easily a resident of Canada. Has anyone been able to solve this before?

I wasn't sure if I should put this in the Canadian or the US Citizen section, sorry if it's in the wrong place.

So I have had a NEXUS membership before I ever moved to the US, and it's up for renewal, but this time I decided to renew it with my naturalization certificate as it satisfied two parts of the application with a single entry, but before that I renewed it as a Canadian. They didn't ask for any of my Canadian documents at all on this renewal, and they did not require me to present a US passport to renew, either. How will it be possible for me to use my NEXUS while going to and within Canada? Aren't I supposed to show my Canadian passport when going in, so I am not flagged as a visitor, when I am in fact Canadian, too?

Basically I'm just super confused as to how NEXUS works as a dualie with both countries that use it. I know that you can get penalized if used incorrectly (even if accidentally), so I want to avoid that.

Good Afternoon Awesome VJ family-

SO we submitted 485, 130, 131, 765, 2 x864, e notification, medical to Chicago per the USCIS website via UPS on May 2nd.

UPS says it was delivered.

Hopefully we'll get the text notification soon.

I'm not sure how this works now.

I'm 95% sure we did everything correct, payments, paperwork etc...

How do we know if everything is good to go and there are no issues with the paperwork? My husband is authorized to stay until June 25th. Will we hear from USCIS before then?

If there are issues do we get a chance to correct them or will my husband fall into unauthorized stay while we correct them?

Just wondering what happens. maybe i'm paranoid.

Thanks

My husband is waiting for immigration interview which can take about 8 months. Now his company is willing to do work visa for him, as they have offices in US as well. Is it possible to change/apply for work visa so late in the immigration process and while awaiting for immigration?
