very often, yes, but not always

pretty much everything east of the old iron curtain has no handouts for immigrants either, at least not much anyway

when i was in prison in 2014 they segregated foreigners and most of my fellow prisoners were from middle east and north africa and they all wanted to go to germany as soon as they got their BG papers

there was some actual migrants, quite a few nice looking african people that i saw around in the years following in Sofia but pretty much all the low lifes and syrians and iraqis and morooccans and algerians passed straight through

a few got shot trying to skip into bulgaria via Turkey back then too, suffice it to say that bulgaria was not friendly to these freebie hunters 

 yes, in bulgaria law at least back then, they had to spend like 6 months in jail waiting for court to decide if they were gonna be sent back

suffice it to say it was effective, there was only about maybe 60 such people locked up with me in the city of Sofia

there was a few syrians in the low sec prison i got transferred to but they were in for criminal penalties, one interesting one was a syrian doctor who was accumulating heroin to convert to methadone to take back to damascus
