many thanks to your answer. I just want to findout if theres new regulation about it, because I went personnaly to doha airport and talk to immigration officer they dont have a clear answer. The last officer gave me a number to contact but no one answer until now. Some says no need stamp visa on our passport if your coming from Riyadh (within GCC). But during my entry to Doha from Philippines my passport was submitted to Qatar Embassy in Philippines for visa stamping.The visa was approved here in doha according to my capacity.Thus I just email it to her a copy.
thanks to qatarliving, some people here answers you honestly to a good path, but some give us misleading answer. Anyway "GOD is behind us".
