This is facts. I didn't know holding passports hostage was a thing until some of the Filipinos who worked the service jobs (barbers, restaurant staff, etc) would open up about their experiences. No communication about whether their work visa will be renewed or if they need to look for another job, can't even get their passport back in any case, and shyt pay.
At the same time (tho this prob applies more to the bengalis) it makes you ponder just how shyt things are back in their home for them to consider it being an upgrade coming to the middle east for this treatment. When ppl ask me how it is working in the middle east, i'm honest in that it's an easy comfortable lucrative life... but to not get it twisted: i got a blue passport and work for a major corporation. If your passport different, good luck.
