Yeah sorry you won't make much money working in customer service. At best, you'll get a job at a call center and even if you manage to become a customer service manager you'll likely make between 4-7k zloty, maybe 8-9k if you're lucky but that's on the higher end. Since I'm going to assume you don't speak Polish, if you wish to get a job in CS you'll likely have to focus on western corporations that have call centers located in Poland. As far as operations management, if you had relevant manufacturing management experience you could get a job.
Most of the guys that come from India and Pakistan tend to go into IT. It is one of the best paying careers and you can easily make at least 10k 12k zloty a month (considered an upper middle class income in Poland - you'll be able to buy certain luxury and save some money especially if you're single and don't have a woman or kids to support). If I were you, I would try to get a job in that. It's going to be way easier for you to take a basic programming course (usually 6-12 months) and upon graduating you'll get a quick offer. This IMO is the best job for non-Polish speakers who wish to migrate to Poland. In my city of Wroclaw, there's a small recruiting company that will train you for 6-12 months to program (I don't think there's any cost for the training aside from maybe like a small paperwork processing fee) and upon completion you take a short programming test and if you pass you get hired for a small/mid size Polish software company at 10k zloty starting salary. IMO, you'll make far more money doing programming than working in CS or OM unless you have like a masters/phd, management experience, preferably know several languages including Polish, etc. in that case you'd be looking at salaries of even 15k, 20k, 25k a month.
Well I am turbaned but certainly not dark skinned ;)
Again, you'll likely just get stares and at worst some name calling by drunk people especially if you're walking around late at night on the weekends. I wouldn't recommend walking alone at night on the weekends as oftentimes the hools (mostly soccer hooligans, blokerzy which are like punk wanna be gangbangers, some skin heads) are looking to pick a fight. You won't experience the shootings and violence with weapons like in US or even UK, Sweden, etc. in Poland but you may be a target for racist drunks coming out of the clubs late at night. Just be careful and be aware of your surroundings. Also, don't be surprised if you try to go to a club or something the bouncers will likely ask you take off your turban. This is for dress code and in a way your own protection as it'll make you stand out less. If you get attacked, don't expect the police to drop everything to help you.
