I think you will be ok, someone correct me if Im wrong, but I believe its the age you are at the time of the application that counts, Obviously some dependent children would have birthdays that take them to 22, but I think its "locked in" at the time of the application. I have a daughter that is 21 (22 Christmas day) so if we had her on the application and it went past her birthday, i cant see any sense in them refusing her.
Unfortunatly, my daughter doesnt want to come anyway, and isnt classed as a dependent now as she has been in a common law relationship for nearly 3 years and has a 19 month old daughter.
I really wouldnt worry, Im sure someone will be posting soon to give there more experienced advice.
