You need to scan all needed documents then send it to them through Email, if you have employer, your employer will do it in your behalf. then the payment or money should be converted to US Dollar or Qatar Riyals can do and payment can be done through international telegraphic money transfer, i think any bank but the receiver should be HSBC-Dubai Branch, you can ask the bank the process of payment through money transfer. don't forget to get the receipt as proof of payment.

Good Luck Kabayan...
