Yes I agree with you ..It help when travelling together To the UK. I highly reccomend this to anybody thinking of bringing their Filipina fiance or wife into the UK. Customs have different approach in regard.
Plus if pregnant make sure you travel with a medical certificate that indicate the state of the pregnancy and the due date..It help incase Customs will decide to send her for a medical. The medical wont take place and customs will let you go with immediate effect.
