Hello, I'm helping some middle school parents in the State of Mexico fill out their child's online application forms. They're being asked to fill out the Custodian Declaration form IM5646, the problem is that the students will not be studying in Canada, they are just visiting as their graduation trip. They are under 18, and I know the parents have to write a specific letter for temporary custody since they will not be traveling with parents. My question is if its mandatory to fill the application or if there was a mistake? What can I do? Thank you.
