In order to optimally cover the requirements of information of the participants about visa when entering Colombia, we have permanent counseling with the Migration Colombia program and its directives in Manizales. According to the regulations of Migration Colombia, to entering the country as visitors ISEA2017 attendees need an invitation letter specifying the destination, the activities within the Symposium and the length of stay. This document should also clarify that the person will be participating for academic purposes and non-profit. As organizer of ISEA2017, the letter will be emitted from the University of Caldas and sent to participants. This letter must be presented in modules Migration Colombia and right there the visitor must make your passport stamped with the special income to attend cultural and academic activities (permission PIP 6). The stamp in your passport will be requested by the production of the event.
