US Immigration from Spain

Hello everyone!
We have almost everything ready to send the K1 visa papers, but there is one question I am not sure about. On the I-129F form, part 1, in the question of other names used.
My fianc has a Korean name which is his birth name and it is the one that appears on all legal documents: birth certificate, passport, credit cards, etc. However, when he moved to the US he started using Justin as it was easier to pronounce.
This name does not appear on any legal document, but everyone knows him by that name. It appears in his emails, social networks and on his business cards. I just call him Justin, never by his original name.
Should we put Justin in the section of other names used, even though it does not appear in any legal document?

Thank you very much!

I have a valid Advance Parole EAD card and I am expecting to be abroad between the i-485 approval and receiving the actual green card. Sadly I have various information that contradicts or in practice makes it impossible.

• There's the risk that the card wouldn't be received in the US in time to ship it to me while abroad.
• Various agents from USCIS have told me that the AP would remain valid until the expiration date.
• CBP has said the approved green card invalidates the AP (therefore contradicting USCIS and showing who has the real authority here).
• USCIS is saying my field office's info pass appointments wouldn't be made in time of my travel, nor are they accepting walk-in due to COVID.
• A lawyer has pointed out it is the green card holder's right to have proof of their status (despite not being able to schedule or walk-in to request a stamp in my passport to prove the 485's approval).

What have you seen, heard or experienced in regards to re-entering the US with an AP card and a recently approved green card, but without the card in-person?

I arrived on k1 visa, applied for social security on the first week of May and they told me it ll take 4 to 6 weeks. I m still waiting for it, my question is can I apply for AOS and other documents like EAD and for travel while my social security is in process?

It's probably been posted before but can't find it right now. How can I get passed the automated system when I call USCIS at 1-800-375-5283, anybody knows?

I know others have been successful in talking to a Tier 2 agent.

We found out today that our petition was transferred from Nebraska to Potomac office, thus meaning longer processing times. We both live in Spain currently and I (US Citizen) received a job offer with a start date of October 2021 and were hoping to both be able to move to the States for my job in the Fall. After the news, I spent the day trying to figure out if we could get it expedited/contact with representatives. My husband, from Spain and in possession of an ESTA visa, would be able to come for 3 months on a tourist visa, but I wondered if instead of trying to rush the processing times (which I know is a slim chance) if there were a way to just get an extended visitor visa while we are waiting? I know I've heard of other couples getting to visit for 6 months in the forum. Is that possible for Europe/US couples? Thanks for any advice ahead of time!
