It depends on what hospital u were assigned. I didnt receive a "congratulation letter" from the director of nursing. The agency just texted me that they received an email pertaining that i passed the interview and i have to take prometric exam. The offer letter i received also came from the agency. All comes from the agency. I dunno what makes the processing so slow. The hmc or the unistaff? The dataflow verification is different from the verification of hamad. They are two different agency. Aside from credential verification of hamad, u have to undergo dataflow verification for licensing of sch qatar.
