When arriving in Quito in anticipation of applying for residency, is it necessary to get an actual T-3 stamp in my passport? Should I ask the customs agent for “una estampa”? On previous scouting trips, I have not had my passport actually stamped as I was only staying for several weeks. Customs just reviewed my travel docs and handed them back. I understand this may be a requirement when submitting my paperwork, which is otherwise all ready to go.
