US Immigration from Philippines

My wife, myself and our two kids are planning on going to the Philippines in December to visit her family. I have some questions regarding this trip hopefully you guys can answer. First question is how long can our US citizen son and myself stay in the Philippines (I assume they still give you the visa at the airport, correct me if I am wrong)? I know last time I went before we were married I had a 30 day visa but I thought if you were married to a citizen it is longer than 30 days. I am asking because I am currently looking at buying our plane tickets and I can get the best price if we stay a few days longer than 30 days.

Second question is regarding covid rules. We are unvaccinated so it is my understanding we will have to have a negative covid test and stay in a quarantine when we arrive. How long according to current rules do we have to be in quarantine and can anyone recommend a reasonably priced hotel we can stay at for the quarantine?

I am sure I will have more questions as we get closer to the trip so I will reply to this post when I come up with more.

HI everyone. I got a letter from NVC dates April 15, 2021 that the received all of the fees, forms and documents that are required prior to attending an immigrant visa interview. As of now, I have not received any letter or email regarding my father's case. Early this year, I called NVC and the person I talked to said Manila Embassy is not releasing interview dates that time. I tried calling US Embassy in Manila last week and it is all voice prompt. I need to talk to a live person and ask if NVC forwarded our case to them. I am so worried that maybe they notified me already but missed it. Can someone give me the phone number of US Embassy in Manila and phone number of NVC. Thank you very much.

What strange requirements may I (the USC) need to keep in mind while waiting for the 33 months to pass so we can submit her N-400? My wife (of 13yrs 2days) got her 10yr GC October 1 and I know she can't leave the country over 6 months or it will count against the 33 months. However, is there any similar restraint for me? I actually just returned from a 5 month trip to the Philippines a few weeks ago because our house/garage and pretty much everything else were destroyed by Super Typhoon Odette in December. She stayed here in San Antonio because we couldn't afford for both to go.

Would there be some future problem with her Naturalization because of that trip? What if I'd stayed longer?

I expect both of us will go back to the Philippines in about June of 23 and she'll return under 6 months but would it be a problem if I stayed longer? Do I really need to be physically present in the US to file the N-400? Do I have to attend her interview?

TIA

We are planning a trip to go visit my wife's family in the Philippines this December and January (If anyone knows where I can find reasonably priced plane tickets let me know) and my wife and step son have Philippines passports that need to be renewed. After months of trying the scheduling website I was finally able to get them an appointment at the Chicago consulate which is on July 11th. My first question is what documents do we need to bring with us and does my minor stepson have to be with us to renew his passport? I know we need the confirmation email and the application form they emailed us but beyond that I am not sure what else we need. The next question would be what are the fees we have to pay and what forms of payment do they accept? A couple other questions I have are will I be able to go in with my wife (and step son if he is required to be there) and how hard is it to find a parking spot in this area? Thanks in advance for your answers.
