People who wish to enter California or anywhere else in the United States in order to engage in certain types of professional work may qualify for a TN nonimmigrant visa. To qualify, individuals must be citizens of either Canada or Mexico and have a prearranged employment opportunity available to them in the U.S. Some of the types of professionals who may qualify for a TN visa include teachers, scientists, pharmacists, engineers, accountants and lawyers.
The TN nonimmigrant classification is part of the economic and trade deals that were set up under the North American Free Trade Agreement that was enacted during the Clinton administration. TN visas allow citizens from Canada and Mexico to enter the U.S. in order to engage in professional work on a temporary basis. People with TN nonimmigrant status may remain in the U.S. for an initial period of up to three years and then seek further extensions of stay.
Applying for a TN nonimmigrant visa is different for citizens of Canada than it is for citizens of Mexico. Because Canadian citizens usually don't need a visa to enter the U.S., they can simply present the required documentation for TN classification to a U.S. Customs and Border Protection officer when they enter the U.S. On the other hand, Mexican citizens will need to secure a TN visa from a U.S. Embassy or U.S. Consulate in Mexico before they go through a U.S. port of entry.
Those who have questions about the TN nonimmigrant classification might want to obtain legal advice about the matter. Employment immigration attorneys can help them to determine whether the employment opportunity that they have in the U.S. will allow them to qualify for a TN visa.
