Making Payment in Dollar
That would require a conversion of Dollars in to Pesos to make payment. Alternately, the payment could be made in Dollars, in which case the Mexican business would then exchange the Dollars for Pesos on their end. Either way, there is going to be some business which takes Dollars and swaps them for Pesos.
That is where the forex trading courses comes in. Transactions like that take place all the time. The market maintains a rate of exchange between the US Dollar and the Mexican Peso to facilitate that activity. Accurately trillions of dollars worth of forex transactions take place each and every day.
