I am holding a HKSAR passport and am currently residing in Canada. I am travelling back home this November and had my tickets bought. I am having a layover in Seattle during my way back to Hong Kong. My passport, however, is expiring by the end of the year. I understand that for normal travelling I will need to have at least 6 months validity on my passport before I can entre the States. Does this also apply to layover flights?
I am hoping to renew my passport once I arrive home in Hong Kong but if I am not allowed to board then I will need to figure something out.
