Generally they are adult women, over the age of 18.
I know for a fact that Filipina women do in some cases have a difficult time entering Singapore, cos i have actually seen it. There were 2 Filipina women in front of me at immigration in Changi Airport, they were getting grilled by the IO, in the end the had to go to the office, dont know what happened.
Immigration might be a lot things, but I dont think they are fascists?
