permanent resident in Latvia
Do you mean "citizenship" with it?
If so, I doubt you could get it easily. You need to spend some time here or prove your relatives were living here earlier; also you will need to spend hard-time exams on the Latvian language, history and culture...
shall I get government or private jobs ?
Mostly, I am sure you will never get government
jobs if you come from another country. Government jobs here are mostly for root Latvians. Even the cleaning work is supposed to the root citizens knowing the Latvian language, only.
So You could only hope for private jobs, and like I mentioned in the other threads, you almost surely will be shagged and digged out in all aspects in the private business, considered like a "nigga"
