we're not yet married coz im still waiting for my annulment. they said if the mother is married (not to the biological father of the child) the child is not eligible to be british citizen even with the acknowledgement of the biological father and his name is in the child birth certificate. and it also says there that you can apply your child a british passport even u didn't register the birth to the uk home office (just provide the notarised birth certificate with the acknowledgment and signed by the father). so to play safe, we will apply our son's british passport after my annulment. our main concern now is what kind of visa we will apply to stay with him in Glasgow and be together again. thank you
