Is it possible for you to mention in what field you want to try your luck here. You see, someone may be able to guide you where to apply there. Coming over here trying your luck with a visit or business visa entails some risks, whereas if you get a job thru an agency will be much better. Visit or business visa has a limited duration and perhaps the present situation is not too conducive for such a plan. I suggest you check the POEA website for jobs available here in Qatar. And if you've applied, just keep on posting here, so that we, your countrymen, or some kind soul here in QL can guide and help you in your job search. At least we can tell you if the company you're applying in is good. Btw, Qatar has committed a lot of jobs to PGMA when she was here. That would be a good start for you to think and just apply there. Well, this is just my suggestion, and it's still your final decision on which route to take. Good luck and God bless you! :)
