My vote would be to remove the word "touch" from all our vocabularies since it is almost never up to date, and just makes everyone nervous.

A case being "touched" is a VJ mannerism that a USCIS phone operator will likely no nothing about. A case being "touched" means absolutely nothing and no stock should be placed in a 'touch' whatsoever.

you are going to have to establish a US domicile as part of this process. If your friend's address is what you plan to use then list that one.

NVC books spousal visas. You cannot expedite because you are pregnant. Your just going to have to wait for the interview to be booked. Call NVC and keep asking if an interview has been booked yet.

"We have not yet lived together" is a proper way to answer this question. N/A means the question itself does not apply, since you two are married, the question does indeed apply.
On my form, I put "We have not yet lived together" and the petition was approved by USCIS with no issues.

You are not the first to forget but is necessary to file the change of address forms. Send off the AR-11 and I-865 now, put your new address on your I-751 application and all will be fine.

I would suggest doing rough versions of all the required paper work first. Figure out what you know and what you don't know. Read over the instructions plenty, and make note of anything pertinent to your case. Get any other required documents ordered/ready. Then wait out that NOA2. Once you get it, do your final versions of your paperwork with any revisions made and send it all out once its time.

Simply have your spouse make the interviewing CO aware at the interview. Also to the CBP officer at the POE.

Together, of course. I just don't know where the myth about sending things separately comes from. It is true that the two packages go to different departments for processing, but I think we can assume that the folks in the intake section can read and send them on their way to the appropriate departments...it worked for me, and for countless others.
Of course I'm assuming you have paid both invoices and that you have the proper bar code cover letters attached...have you done that ??

Don't leave it blank, doing so could result in an RFE. My wife doesn't have a middle name, so what we did was put dashes through that entire box for a middle name. I would suggest doing the same in the last name box for your wife's form.

They don't usually read the cover letters so no stress.

Slim to none-- they are looking for TB

For the I-130 you only need a copy of the marriage cert. not the original or certified copy.
The IV packet you need to send an original and a copy (not certified) a plain regular copy.
At the interview you will get your originals back but it's good to have another original just in case they ask for it.

Congratulations.

Then how do you plan to just go live in Canada on a US green card? You would not be living legally in Canada that way. A US green card is for living in the USA, not for living in Canada. You need proper documents to be able to live in Canada. Your story makes no sense at all and sounds like a huge fast track to lose your Green Card and get in trouble but you seem to not care what so ever.

This sentence:
is not necessary. Everything else looks good.

The Canadian company is willing to sponsor not only the USC for a work visa but you too? You cant just move there with him, they need to get you a visa as well. Immigration works the same way in Canada as the USA. Cant just randomly move to another country because your husband lives/works there. This means you have to maintain status in two countrys accordingly. Theres a lot of research you needa do on this and my advice is to just look for a job in the US and disregard the Canadian job. You will get caught at the border at some point and they will take your green card away because they will figure you out. CBP are not idiots.

Do NOT listen to those lawyers--these cases rarely cost less than $5000, and often much more. LISTEN VERY CAREFULLY--you must go to www.immigrate2us.net as suggested before and you MUST talk to Laurel Scott--she is among the very best for this type of situation.
DO NOTHING else before you talk to her--your whole future hinges on it.

Most Canadian airports have customs preclearance facilities. When there is a preclearance facility, customs procedures will take place there.

At this stage IMO you are fine; they would have returned your package as soon as they received it if it was too early. Now you just wait. Good luck!

As milimelo suggests, do it as soon as possible.
You should have done this within 10 days of when you move .
That's a condition and responsibility for you as a GC holder.
In any case since you didn't USCIS may forgvie you but to avoid further complications and to receive the 10 year GC at your new address and all other correspondence please file AR-11 online as soon as possible and don't forget to mail the I-865.

AR-11 for immigrant filed online. Confirmation online, print it out - nothing will come in the mail.
I-865 filed for you as the sponsor (have to mail this in, will get a confirmation letter).
Use new address on the I-751.

Not as of August 15th. Canada does not have a USCIS field office. If there is no USCIS field office in a country as of August 15th, then the I-130 and accompanying paperwork will have to be sent to the Chicago lockbox.

What I suggest is to complete the top two available lines with the information about the latest two visits. On the third line type or print the following. Multiple visits since 19XX. No overstays. The year entered should be the year of first visit to USA. If not sure, add the word "about" before the year. Works every time I've seen it tried.

If I were in your shoes, I would consider this a non-issue and enjoy your visit. Nothing to see here. Move along. Really.
