Thank you Kabayan!

I would like to clarify;

1. Does my wife Birth and Degree certificates are part of the required documents?
2. For my child, birth certificate in red ribbon only?
3. I will send those documents to Qatar Embassy in PHL via DHL for stamping and bring it here for visa application. Does photocopy will suffice or I should have the original?
4. If I received the visa, can they travel using photocopy of visa or they must have the original?

Best Regards.
