Sorry...just noticed this thread.
Yes, I wrote a letter to the ECO in Manila concerning the entry clearance for my step-daughter, who was 7 years old at the time (wife having not declared that she actually HAD a daughter on her spouse visa paperwork a few years before).
My explanation was accepted, and settlement visa issued. She has a British passport now...plus 12 'O' and 4 'A's, AND a degree from Nottingham Uni'.
The little waif from the province done well.![]()
