Hello, you cannot legally work on a pensioner’s visa. So perhaps you might want to rethink your visa strategy and opt, instead, for a professional visa. You should probably contact an immigration attorney or a visa facilitator to get the latest information. Check to see if the university you recieved your degree from is on this list: http://www.educacionsuperior.gob.ec/…/LISTADO…
A visa facilitator in Guayaquil who has handled a lot of these and seems to be very on top of all this is Dana Cameron: agua_plata@hotmail.com — she processes a lot of visas for people who live in Cuenca and along the southern coast, but she appears to be very good about answering questions.
