.. so... a few points
Greece is a Schengen country... but UK is not.
Hence she could travel to most countries in Europe (where they could meet),
but obviously NOT to the UK.
Why does she need to send him the filled-up forms ?
It is SHE who needs to submit them, not him !
In usual cases, SHE would submit in the Philipinnes, and have to get the obligatory
bio-scan.
Perhaps she may be able to submit to the UK Embassy in Athens, so she should
investigate that.
Confused ? ... yes .....
