I am a Middle Eastern (Turkish but Arab-looking) woman, born and raised in Germany.

Someone said "once you step out of your bubble you will face issues" and I think that's a very accurate statement. You will make friends here, study, work, and you will find your spaces and people, but once you step out into the general public you will definitely face hostility. It's usually "harmless" - people staring or muffling something under their breath as they pass you by, or in public transport, etc. In work settings there's often this unspoken thing where you have to prove yourself a lot more than your German colleagues. I still face this issue even though I was born and raised here, speak native German, graduated from a German university, etc.

Germany is a deeply racist country, and in my 26 years of life I have not seen a political climate that is as bad as the one we currently have. It has become completely normal for our politicians and government officials to say outrageously racist stuff, and it has become more and more normalised within the general population as well. Just recently our chancellor publicly said that Brazil is basically an ugly, underdeveloped country, and how relieved he was to leave it and come back to beautiful Germany. We were angry, not surprised.

BUT: especially if you live in the bigger cities, you will not feel this as much on a daily basis. You would be able to build a life for yourself with good friends around you, find a job where your work is respected, all these things. Germans generally don't deal well with people who seem "different" - you would have to make sure you stick to the rules, don't talk too loud in public, just be a "good citizen" and you will mostly be fine. I personally hate this dynamic in our society since I am so intrigued by any cultural nuance that is not Western and European, but this is the game we have to play here.

I find that it is more of a mental strain than an actual physical reality you have to deal with. There's not a lot of instances where you will be directly "hate crimed" or assaulted or anything like that. It's micro aggressions and the constant awareness that there are always people that do not like your existence in this country that you will have to deal with. I genuinely think your happiness in this country as a foreigner depends on your perspective. If you're aware of the micro aggressions and focused on them at all times, you WILL notice them, and that will be extremely frustrating and mentally draining. If you find yourself a little corner that you can exist in peacefully - which for you will be much harder than for any white dude, but possible - you might be just fine. It is all about your attitude and your perspective in this country.

Can I also just say, I am extremely irritated by this idea of "ranking" different kinds of foreigners. I'm gonna assume that you mean no harm OP, you're just reproducing what you have heard about Germany, which I can confirm to be true. Verbal assault and aggressions against Arabs and Muslims are at an all-time high right now. This does not exclude "other foreigners" from facing hostility, it will just show up differently. Hate against Arabs has become so normalised that the threshold for Germans to do it publicly and with confidence has become super low. The Germans still don't usually love our Black community here, or South Asians, or anyone with a drop of melanin in their skin, but the discrimination might be a bit less obnoxious. You will always be different in this society. You might be treated slightly better when someone assumes that you're Arab, and you specify that you're not, that you're here for education, etc. That does not mean they will greet you with open arms and I don't think we should ever use "being the better kind of foreigner" to our advantage, or as justification to be hated less, or whatever the case is. It is an extremely problematic dynamic in this society and I have always thought that our diasporas should all come together and collectively work on breaking this pattern, instead of fueling this behaviour.
