CFO is something that any Filipino must complete before leaving the country for any type of immigration intent.
Yes, we had to do the medical again Fortunately, she was not flagged for sputum the second time. Our biggest issue was the covid shutdown. We did everything we could to try and reschedule the interview after having to go through the sputum. a little over 3 months later we finally got scheduled. We got a 221g and by the time that was fixed and they were ready to issue the visa we only had a few days of validity left and it did not give us enough time. The embassy said retake the medical and then they would issue the visa. Everything went smoothly from there.
In your case she has the visa. If she does not use it before it expires it will be a more difficult process. That's why everyone here is suggesting to do anything you can to get the CFO on Monday. Hopefully they will take pity on her and let her through.
As far as greasing the wheels, that is common in a lot of things in the Philippines, but don't even think about it with the CFO.
