The other three categories of contractors are entitled to work permits through the R204 (a) that exempt persons who are granted entry under an international agreement between Canada and other countries from the LMIA procedure. Administrative codes were assigned to each category. The expression of a definitive intention of an applicant to return to the United States or Mexico when distributor status ends is generally accepted as sufficient evidence of a temporary intent, unless there are signs to the contrary. USMCA countries must comply with IMF standards to avoid exchange rate manipulation. The agreement requires disclosure of market interventions. The IMF may be summoned as an arbitrator if the parties argue.  On April 3, 2020, Canada informed the United States and Mexico that it had completed its national process of ratifying the agreement.  NAFTA has increased Mexican agricultural exports to the United States, which have tripled since the implementation of the pact. Hundreds of thousands of jobs in the automotive industry have also been created in the country and most studies [PDF] have found that the agreement has increased productivity and reduced consumer prices in Mexico. Chapter 16 facilitates the temporary entry of citizens of the United States, Mexico and Canada whose activities are related to trade in goods or services or investments.
NAFTA is a reciprocal agreement and Canadians will receive similar treatment when they enter the United States or Mexico. Chapter 16 is not a substitute, but complements our existing general provisions. A U.S. or Mexican business person wishing to enter Canada may be considered in accordance with NAFTA and general provisions applicable to all foreign workers. Since NAFTA, trade between the United States and its North American neighbors has more than tripled and grown faster than U.S. trade with the rest of the world. Canada and Mexico are the top two destinations for U.S. exports, with a share of more than one-third. Most estimates conclude that the agreement has increased U.S. gross domestic product (GDP) by less than 0.5%, which equates to an additional $80 billion over the U.S. economy, with full implementation or several billion dollars of additional growth per year. On December 9, 2019, Fox News reported that negotiators from the three countries reached an agreement on implementation, paving the way for a final agreement within 24 hours and ratification by all three parties before the end of the year.
Mexico has agreed to impose a minimum wage of $16 per hour for Mexican auto workers by a „neutral“ third party. Mexico, which imports all of its aluminum, also objected to the provisions relating to the U.S. steel and aluminum content of automotive components.  On June 19, 2019, the Mexican Senate ratified the agreement (114 yes, 3 no, 3 abstentions).  Mexico`s ratification process will be completed when the President announces its ratification to the Federal Register.
