cannot renew AppleCare+ in foreign country

Although in settings of my Apple account/Media & Purchases are set to the U.S.; General/Language & Region are set to the United States; my phone was purchased in the United States with AppleCare+ for 2-years; the phone was stolen November 2024 and I received a new phone via AppleCare insurance company, but I had to set it up in the foreign country I am temporarily residing. The coverage expired in January and I tried renewing, but it continuously tells me that: AppleCare+ Not Available (in small text: AppleCare+ plans not available in your region).

How is it possible that a U.S. citizen cannot purchase coverage for an iPhone purchased in the United States and but has to work outside the United States?

I have had varying levels of customer support including Senior Support(for which we were disconnected with no call back). This is quite frustrating.

Now I know why people switch to android phones. They are cheaper and do not have the level of difficulty used by Apple and government restrictions.

Thanks, if anyone can help. If not, it's just life and I will have to move on to another solution.
