Open Junior ISA & leave U.K.

Hello, I'm living in U.K. on Tier2 Visa. I intend to open Junior ISA for my children. I've 2 questions: 1. I would like to know the implication on the Junior ISA in case we leave U.K. I understand that one can leave the normal ISA open (but not contribute to it). Is it the same for Junior ISA (even for non-UK citizens)? 2. Can the children avail the benefits of Junior ISA after they turn 18 regardless of their nationality & residency (i.e., in case they're not residing in U.K. when they turn 18years old)? Many thanks.
