Greetings friends, my Venezuelan girfriend could not obtain US Dollars from the government currency system (CADAVIL) in time for her trip to the US leaving Dec.16 from Caracas. She flies first to Bogota where she picks up her transfer to Houston, Texas and then to Newark, N.J. Is it even possible for her to exchange her Bolivars for Colombian Pesos and then to Dollars or from Bolivars to Dollars in the Airport in Bogota? She has a 5 hour layover from 8pm to 1am.I know this is not the best option ideally but it might be her only way to get dollars for her trip. I would greatly appreciate if he you have any information. Thank you.
