Sorry, but you are starting over.
With immigration you really need to pause, count up to a 1000 and then proceed with action. Especially if it's a cancellation.
Mmmm... Not 100% true. Officers have discretion to ask about travel to other countries as a way to prove that the applicant is not just trying to establish themselves in another country.
What country are we talking about? That's important information that will give you a more accurate reply.
Is there an age difference?
Has the petitioner applied for a visa before?
This person has already filed their 751. And no, it does not always "stick". When I filed for N400, a year after my 751, USCIS sent me to my older State for biometrics.
My 751 was approved about a month before my N400 interview. I do not remember the wording of the interview letter, but I did attend with my husband and I am glad I did because the officer did ask to see him. Officer made it clear he was unaware of the approved 751, so maybe your situation is similar. I would not worry (but I would go with my spouse)
No, no need to bring them and often seen as a nuisance in the context of a formal interview. However, do bring documentation that proves that the children were born to this marriage, such as birth certificates, school records, and family pictures.
Seems the system is: call and get an appointment. Once you have that appointment, you can attempt to do an early walk in. Which makes no sense to me but I guess no one cares what I think.
Maybe the reason why I was able to do an early walk in is because indeed, I had an appointment at a later date, and I hadn't missed any previous one. But I don't remember the people at the ASC telling me anything about it. They just listened to my rant about why the f#### they'd sent me five hours away, and that's it.
I would not travel, but maybe your risk tolerance is higher than mine. Yes, you do have that extension letter that allows you to travel and work in the country with an expired green card, so long as you attend the biometrics and USCIS has no reason to deny you.
A lot of undocumented immigrants work in the country, and they still work here. Just because A is true it does not mean that B is true. But I digress.
Hopefully your appointment will come in before you leave. Or you can try a walk in at a different location.
So I will try to make this story short. We moved from WV to Ohio back in 2021. Surely enough, I notified USCIS of my new address. I even filed the 751 from our new address! And got all USCIS mail in my new address. But somehow when I filed for N400 they sent me to WV for my biometrics for February 23rd. WV is about five hours from me. So the first thing I did on that Friday when I received the biometrics appt is to call USCIS misinformation line and told them about the situation. The lady said “oooh don’t worry, I’ll send a request to reschedule you to your closest ASC”. She just laughed it off in a way. I have an ASC that’s 20 minutes from my house. So I decided to ignore her advice on the phone not to worry, and took matters into my own hands. I did a walk in first thing in the morning that Monday, and I’m glad I did because they never rescheduled me.
