US Immigration from Peru

Hello, does anyone here filing in April? just to check and share timelines?

For question 1 under Part 3 of the I-485 ("have you ever applied for an immigrant visa to obtain permanent resident status at a U.S. Embassy or U.S. Consulate abroad?"), I'm pretty sure applying for a K-1 visa doesn't count, but I wanted to check to make sure. I submitted an I-129F for my fiancee (now wife) but it only went to the NVC and we have withdrawn it. Since the K1 is a nonimmigrant visa, and we didn't apply at the U.S. Embassy, I am assuming the answer to the question is "no"?

We have to send in a total of $1,760 in fees (forms 485, 130, and the biometric fee). Can I put it all into one check? Or should I write separate checks for each amount (i.e. $1140 for the I-485, $85 for the bio fee, and $535 for the I-130)?

Hello! I read in https://www.uscis.gov/i-9-central/form-i-9-related-news/temporary-policies-related-to-covid-19 that because of pandemic delays one could start working with the EAD approval notice since the actual EAD is taking a long time (surprise to no one) to be mailed.

My questions are:

1) is this still valid? The last related entry is from November 2020 and I think it was until February 2021. https://www.nafsa.org/regulatory-information/temporary-use-i-797-approval-notices-due-covid-19-ead-production-delays

2) I know the EAD is used as both an employment authorization and a travel authorization, so can the I-797 EAD approval notice also be used for traveling outside the country? or do we need either the EAD or the AP?

Thanks!

My spouse is applying for AOS and is submitting a I-131 with the application. For Part 4 how detailed or important are parts 1.a and 1.b? She will want to go to Peru to see her family/grandparents but would also like to travel to (who knows where now) some other places for vacation. Should we list countries like Mexico, Italy, etc. for vacation and say "vacation" in part 1.a? Or just list Peru in 1.b and say for 1.a to visit family?
