First and foremost advice is that do not quit ur job unless u get a job here. take vacation from ur current job and take the chance, in that way u won't be taking risk of being jobless. secondly ask ur friend to do some homework before u come here like if he has terms with other people where he can refer u for an interview, that would be great. and if he can not do that then u will be left with the choice of visiting different companies yourself, drop ur cv there and walk in interview sort of things, which is also not a bad idea. other than that i can suggest u to check websites of different companies in qatar and check their employment criteria and apply online as well, like qatar petroleum, mersk oil and may other oil n gas companies in qatar, check their websites. chances for engineering jobs in qatar are bright but as u mentioned u have only two years of experience it will be really tough to get a job as in your field experience does matter a lot but it is not impossible. there is no harm to give it a try at least. regarding visa I have limited information, which is, the tourist visa is only for one month and it can't be extended but if someone is sponsoring u from here and u come here on sponsored visit visa then it can be extended. for more accurate information u should check with the travel agents. what i am suggesting u is that u should give it a try rather than not trying at all but just don't quit ur present job unless u have one here. Good Luck
