Do immigration requirements exist for U.S. citizens traveling to the border on business?
With some limited restrictions, U.S. citizens can work in a Maquiladora manufacturing business. Visas are required and can be readily obtained with a passport and/or birth certificate at the border crossing for up to six month visits. It is also possible to obtain annual visas for longer-term workers or frequent visitors. Surprise inspections are done in plants by the authorities, during which inspections, visas are checked. Doing business in Mexico without a valid visa is not advised. Penalties for noncompliance can be significant and typically include deportation. Many plants in Mexico have U.S. executives and technical personnel who live in the U.S. and commute to Mexico daily.
