I would like to ask you about a matter.A few days ago I received via email a contract from " Awsaj Academy" and they send back to me an invitation letter which I will send it back via email also to a bureau of immigration services called " Dalma" . I am asking now it can be a scam ??
There is a very good chance of this, if you were not in correspondence with them before. Generally, businesses don't just send people contracts. I wouldn't send them any of your personal information, and I would definitely say you must not send them any money. While Awsaj is a real school, somebody may be using their name to trick you.
The best thing to do would be to contact Awsaj directly via their official website (comes up first on the Google search).
There basic rules to follow are, it is always better to be safe than sorry, and if it seems to good to be true, then it probably isn't true.
I can also recommend that you educate yourself about how things work there, so that you are prepared if somebody tries to fool you. See our Qatar guide, which starts with Moving to Qatar
Best of luck, hope it works out.
Kind regards
