Just for fun, I've googled "Ukrainians in Portugal" - and found plenty of stuff.

I apologize for assuming that most of Ukrainians work there illegally - many do have permits, it seems:

There are an estimated five million Ukrainians employed abroad, chiefly in Greece, Italy, Portugal and Spain. Ukrainians moved to Portugal in part because some of them learned Portuguese fighting anti-colonial wars in Africa; Portugal and Ukraine in February 2003 signed an agreement that will allow some of the estimated 200,000 unauthorized Ukrainians to become legal seasonal workers.
