I have spoken with some people lately saying their friends have registered their children as BOT citizens, thinking that this will benefit them.
With some exceptions, it is usually a very bad idea for non-Bermudians to register their child as a BOT citizen.
Only naturalised BOT citizens count as Belongers, and this can only be done as an adult. Registration as a BOT citizenship will therefore not improve the child's immigration situation and, worse, will cut off the possibility of naturalising as a BOT citizen as an adult, as you cannot become a double BOT citizen.
