THANKS ALOT FOR YOUR COMMENTS..
Can i provide them doucments for visit visa sponsorship from my brother as i will stay at his home instead of hotel booking?

Secondly its only a visit of 15 days max..so i dont think there is any doubt about my ties with Qatar..

How long is the visa process and wht is the minimum bank statement i require?

Lastly can you provide me address for visa office here(email or mail address,contact #)..

thanks all in advance
