I believe the present Malaysian Petain girls have this special card by AV. They are allowed to work in Sinkieland as pros for as long as they want provided they pass their health screening tests and abide by AV rules during their off days. No going out for hotel bookings with their customers outside working hours. But for the Thai, PRC whores at Geyland, they are only allowed to work for 2 years at the legal joints there. Same rules, no special bookings outside their working hours. No going out with customers. No romantic relationship with Sinkie gong gong man. After 2 years tour of duty in Geyland, they will be sent back home. Few days before going back, they need to surrender their passport to ICA. Then at the airport during check in, ICA would then return them back their passport before they board the flight. They are barred from visiting Singapore for 2, 3 years.
