Just remember - the minute anyone asks you to pay any money to process a visa, purchase a ticket, registration fee etc then you know 100% it's a scam and to pull out IMMEDIATELY. Don't be another victim of the recruitment rackets. All recruitment in Qatar by law must be free of charges to the candidate. The employer pays the agent a commission, the candidate pays nothing. If they try to tell you something different they are lying and you will know for sure you are being ripped off.
