If visiting Kazakhstan is it required to have a consent letter to leave and/or enter if minor child is traveling with only one parent? (Using visa-free entry permission).
Child is a US citizen, 14 years old, would be arriving from Mongolia (which does not have a consent letter requirement). Airline T&Cs do not mention such a requirement, and a customer service rep told me the airline doesn't require it for boarding "but Kazakhstan might require it, you should check". I have posted this question here concurrently with attempting to get an answer from the Kazakhstan embassy.
