Is history of cancer an issue and make a parent inadmissible due to medical grounds if mom has history of cancer treatment?

Thank you.

Didn't see a June 2022 N-400 Filers group, so thought I'd start it.

Also, saw some folks saying they had issues at interview if they filed the first day of their 90-day early filing window. Anyone else have that issue? Since last week, I also received an update that my pending I-751 has been transferred, assuming to the local office that will process the N-400.

For report of marriage in US we had to go to the New York City consulate due to us being married and living in Pennsylvania. Washington DC would've been closer and easier but somewhere we were instructed we had to go to NYC.

Now we need to go again for an affidavit of support and consent and special power of attorney for a minor child getting a new Philippines passport. Can we go to any Philippines consulate or embassy for that, or is it based on state like the record of marriage?

Thanks!

One of the questions asks if you've ever been arrested or detained by any police including immigration officers:

 Have you  EVER  been arrested, cited, or detained by any law enforcement officer (including any immigration official or any official of the U.S. armed forces) for any reason?

What does this mean exactly? If you were held at the border for suspicion while you were just a visitor (non green card holder) and questioned for a couple hours and fingerprinted, but then were allowed entry - does that count as a yes on that question?
This was over 10 years ago as well.

Because then in a later portion it asks for evidence:

 Information about your arrest(s) If you have ever been arrested or detained anywhere in the world, by any law enforcement officer, for any reason, and no charges were filed, upload clear images of these documents:  An original or court-certified arrest report An official, certified statement from the arresting agency or applicable court confirming that no charges were filed

...but I was allowed entry. I think they stamped my passport at the time with a 2 week visa, but that was it.

Just got my extension letter. Do we now have to carry this everywhere we go (when not travelling) along with the green card?
