Foreign visitors planning to go further than 25 miles (about 40 km) inside the United States need to apply for a permit upon entering the country. At the Colombia entry port, the I-94 permit can be requested, with the office hours being the same as those for the Puente Internacional Solidaridad Colombia, from 8:00 a.m. to 12:00 midnight every day of the year. The cost for an I-94 permit is $6. The permit can be issued for a maximum term of 6 months and for multiple trips to the United States. Up to seven days before traveling to the United States, you can advance the I-94 process and payment online, instructions at this link: https://i94.cbp.dhs.gov/I94/#/home More information can be found at these links: Official I-94 site https://i94.cbp.dhs.gov/I94/#/home Information on applying for and paying for the I-94 online https://www.cbp.gov/newsroom/national-media-release/cbp-hace-disponible-v-internet-la-solicitud-y-pago-de-la-i-94-para Secretary of Foreign Affairs: Traveler recommendations https://consulmex.sre.gob.mx/sandiego/index.php/otrosmenu/viajando-a-usa/permiso-i-94
