be careful.. do not ever surrender the original red ribboned education certificate stamped by phil embassy & MOFA -qatar... you are required to submit a copy only... make sure you have also copied the stamps from phil embassy & MOFA-qatar...the labor dept of qatar does not require the original... you will only have to show them the original but they will not take it from you...keep the original with you... the red ribboned educ certificate has no expiration contrary to what other filipinos say... remember it's not that easy to get authenticated documents...moreover, you will also need authenticated NBI clearance (red ribboned & stamped by phil embassy & MOFA-qatar).. this time you can surrender the original as the NBI clearance itself is valid only for 1 year...
