From a US perspective. Depending on the specialty a PA will do 99% of what a doctor does. In more surgical specialities they tend to do most of the pre and post op work. The US also has NPs (nurse practitioners) which are very similar in function to a PA. The big difference is that an NP is taught medicine from a nursing perspective, while a PA is more explicit in the partnership with a doctor. As a PA or NP you would be more of a peer with a doctor, so you would likely see different sides of doctors and nurses than you currently do.

You can expect different drama, maybe not less. I can’t say what specifically would be the case in Germany. In the US it’s mostly about balancing patient care with paperwork, and battling insurance companies. The ratio of practicing medicine vs bureaucratic bullshit is currently very skewed towards bureaucracy in the US.

There isn’t much you can do at raid time. Interference is a crime. What you can do, but it may still cause problems for you.

1. Alert their locations as much as possible.
2. Film them at a reasonable distance and use an app that syncs to cloud instantly.
3. Report police stations, jails, and prisons as placed you believe could be harboring illegal immigrants.
4. Speak non-English languages first around them.
