Yes, if they are flying in from the Philippines, the copy of the approved Business Visa will need to be sent to the Philippines where they can finalize the process to exit their country.

Processing a Business Visa application in Qatar can take 1 day to 2 weeks, or more...

Once a Business Visa is approved, the individual has 3 months to arrive to Qatar before the validity expires. If they do not arrive within 3 months, the entire process must be restarted.

Once the individual arrived in Qatar, they can stay for an initial 30 days, extendable twice, for a total of 90 days before they will be required to exit Qatar.

Hope this helps!
