To immigrate to Mexico, US citizens must first obtain a visa. There are a number of different types of visas available, depending on the purpose of your stay in Mexico. For example, there are visas for tourists, business travelers, students, and retirees.
Once you have obtained a visa, you must then register with the Mexican government. This process is called "empadronamiento." To empadronar, you will need to present your passport, visa, and proof of address.
After you have empadronado, you will be issued a Mexican residency card, or "curp." This card is proof that you are legally resident in Mexico.
There are a number of things to consider before immigrating to Mexico. For example, you will need to find a place to live, learn Spanish, and get a job. However, if you are prepared for the challenges, moving to Mexico can be a rewarding experience.
