The aim of this work is to analyze the reception of remittances in Mexico as a component of the migration phenomenon. We seek to understand the economic effect from the economic-fiscal policy and its relationship with exports after the entry into force of the USMCA. We applied the time series forecasting method using an unseasonal ARIMA model. As a result, we understand the correlation between remittances and exports, although there is also a prevalent benefit in fiscal income for the treasury of the country of origin.
