> Do you feel welcome in Germany? Just curious.

Yes. After living even in a "conservative" town, I feel more welcome than I feel in the city I was born - Istanbul. In my first 5 years, I usually had to ask people to speak to me in German, they usually switched to English to make me more comfortable. Sure, I can give many examples of racism but the great thing about Germany is that racists aren't significant threats to my rights as a resident. Also, I think back in Turkey, there were many more cases of racism - it's just that they don't get any attention among "bigger problems" (what being a bigger problem is another topic I'd rather not dig into). After all, I'm happy that here people are ready to discuss such things.

> Why are some of us expats while others are merely "immigrants"?

I would guess if you came here to advance your career, then you are eligible to be an expat. Of course I'm kidding. I think many people, for not-so-evil-but-still-a-bit-disturbing reasons, would not like to be called an immigrant. I actually do not care and am happy with the word.

The difference between an 'expat' and an 'immigrant' is that an expat made their choice from a position of strength and an immigrant made their choice from a position of weakness.

That's really all there is to it, everything else is exactly the same. Though usually people from wealthy countries would not like to be known as 'immigrants', they are expats, of course.
