it is not filipino who are selling this  visas.. most of them are bangledish, indian and nepal.. they just want to sell it to filipino because mostly of company here in qatar believes on the ability of filipino. i think all nationality in some point go out look for agency who can sponsor them, their friends or relative rather on doing the right way as you said.

the problem with you is you believed that only filipino is doing this, why not ask other people. maybe you was not able to buy one from a filipino so you generalize the situations.

the visa that the agency released is legal. it was processed and obtained legally and was approved by qatar government.
