Ur profile states u are from US of A .... I think 6K a month may not be good enough.... but again depends if u are different than how people from US of A are generally presumed to be living...then may be just OK.

for more detailed analysis just click on the link "sample budget & cost of living" on the right side of this site under "Guide to Qatar" ...and u can workout things depending on ur requirements..

Wish you luck and welcome to Qatar in advance if u finally make it...
