Even if you’re downloading the file directly from the URL found in the RSS feed, that doesn’t mean that ads can’t be dynamically injected into the file. A URL like https://download.my.podcast/episode4.mp3 can still be answered by a script that serves a custom version of the podcast with region specific ads.

In that case you should contact a professional who has done this thing before. But be aware, it’s quite expensive. This site, for example, charges 749 €.

The IRS has a special procedure for this case called “streamlined procedure”. Unfortunately it’s a little complicated and you have to pay close attention to all the required details.

Since OP was never an American resident or paid taxes, he or she shouldn’t need to file taxes or be flagged on a system for anything anyway.

Unfortunately the US is one of two countries that requires all citizens, regardless of past or present residence or employment, to pay federal taxes.

I can imagine that some authorities might find it suspicious, but in OPs case, it is necessary to travel with both passports to have the least hassle.

Entering the US with your German passport or returning to Germany with your US passport if you have both will lead to a lot of questions as you won’t have the necessary visa in those passports.

Edit: Although I wouldn’t present both passports at the same time, only the one that is applicable or more convenient for wherever you are.

Always enter and exit the US with your US passport. Not doing so is illegal.

For anything else, use your German passport, especially in the EU. That’s what I have been doing for years.

I don’t know if it is an issue for immigration, but you absolutely are required to file taxes every year and can get in trouble if you don’t. There’s a “streamlined procedure” that you can do if you’ve never filed taxes to start filing without incurring any fines or penalties.

I don’t know, Apple releases a “new” version of macOS with big fanfare every year, and I’ve never heard anyone complain about it as if it were a huge breaking change.

I switched to a TKL (tenkeyless) to reduce the distance between my hands when my right hand is on the mouse, and it feels so much better.

I got a programmable keyboard, so I remapped the keys around where my right hand rests to be the numpad keys when I hold the capslock key. That way I can still have the convenience of the numpad without having an actual dedicated numpad, although I’m still getting used to using it this way.
