hi kyledr… philippine immigration are very strict nowadays unlike before, 5 years ago.Questions and to respond intelligently to your interview are no longer the basis to pass the severity of their "laws". You should hold a company visa (issued from a company based in Qatar) and POEA assistant is imperative. You may also travel to Qatar through Family Visa which is arguable, meaning you dont have to explain further or waste time in Philippine Immigration. This assertion of authority is due to the Filipinos who came to Qatar with tourist or business visas, seeking luck but end up unfortunate and keep on complaining to POEA where in the first place its not POEA's fault.

Anyhow, just bring all your documents such as visa, passport, etc. and show money...wish you all the best.
