I will apply for a Canadian ETA since I have an American visa and I'm eligible to. In this process, will I need to submit my passport to a Canadian embassy or will the ETA be digitally linked to it?
Second question: My visa will expire in ~5 months, so I will apply a new one. Should I wait to have my new passport to apply for my eTA? Is the eTA linked to the passport and becomes invalid after a passport renewal?
Useful information:I have Brazilian citizenship.
