only half way back mrshark,
your right in a away, if she had more time on her visa, maybe she could apply for A COA to wed here, but you could be waiting months for that then more months to apply for FLR, probably alot quicker for her to go back and apply for a fiancée or spouse visa if you want to wed and do without a lot of waiting and heart ache but if shes here already might be worth trying to extend her domestic worker visa and see if you really want to wed b4 it ends
