urwaywardgirl:
would like to know everything that is to know about Latvia
I have bad news for you.
Noone could know
everything!

Whatever I could tell you right now:
- biggest part of the current students will leave Latvia for a better living
- currently only Riga has the smallest amount of unemployed (~2-3%); smallest Latvian cities could have it in range 15-20%.
Check this topic for more, we have explained it all wide there:
Would be easy to get a job after studying in Latvia?Without Latvian skills, in short, you can't apply for any job.
