Child is in elementary school, and the reason is higher standard of education compared to country of origin. The father works and stays in country of origin and will be the one sponsoring(fees, flights to and fro during school breaks, accommodation and all other expenses. I read of the possibility of the accompanying parent being able to stay with the child on a trv as the custodian which can be allowed for the duration of study for elementary school which the visa is given for only 1 year and needs also to be renewed. Couldn't find any other provision that shows the I admissibility of the accompanying parent as the custodian living with the child. Whole family has very good travel history and immigration record for other countries. I would just like clarification if I'm wrong regarding what I read. Thank you for your response
