The Plant Decides the City
A TN role is tied to a specific employer and a specific job, so the real question is rarely which state you would like to live in. It is whether you can build a life in the city where the plant is. Each of these states is also many places at once. El Paso and Houston are both in Texas and feel nothing alike, and the same is true of Bakersfield and San Diego, or Tucson and Phoenix.
What the three states do share is closeness to Mexico, long-established Mexican-American communities, and Spanish heard in daily life. That makes the move easier in some ways. It does not replace the work of settling into a new country, a new plant and a new routine.
This guide compares the three at state level using official sources, then covers what to check about the specific city once an offer has a location on it.
What It Costs to Live in Each State
The U.S. Bureau of Economic Analysis (BEA) publishes Regional Price Parities, which compare price levels in each state with a national average of 100. The latest figures, for 2024, were released in February 2026.
The gap is far wider for housing. BEA's housing index, which tracks rents, puts the three states much further apart than the overall figure does.
| State | All prices (U.S. = 100) | Housing (U.S. = 100) |
|---|---|---|
| California | 110.7 | 154.3 |
| Arizona | 100.7 | 106.8 |
| Texas | 97.1 | 96.5 |
Two cautions. These are state averages, and metro areas vary widely within each state; BEA publishes metro figures as well. And prices are only half of the comparison, because pay also differs by state and by occupation. The Bureau of Labor Statistics publishes wages by occupation and state through its Occupational Employment and Wage Statistics program, so compare any offer with the figures for your own discipline and location rather than with a national number.
How State Taxes Change Your Paycheck
Federal income tax applies in all three states. State income tax does not work the same way in any two of them.
| State | State income tax, 2025 tax year | In practice |
|---|---|---|
| Texas | None | No state income tax is withheld from your pay. The state sales tax is 6.25%, and up to 8.25% with local sales taxes added. |
| California | Graduated, from 1% to 12.3% | The rate rises with income, and the tax is withheld from each paycheck. |
| Arizona | Flat 2.5% | One rate for all income levels and filing statuses. |
A state without an income tax still collects revenue in other ways, such as sales taxes and local property taxes, and renters pay property taxes indirectly through rent. Look at the whole picture, not one line of it.
Your first U.S. tax year can also be more complicated than later ones. You may have income in both countries for part of the year, and your U.S. tax residency depends on how many days you spend in the country. A tax preparer who regularly works with professionals from Mexico can save you a great deal of time in that first year.
The First Month: Paperwork That Varies by State
Some of the hardest parts of the first month are administrative, and several of the rules are set by the state rather than the federal government.
Driver's license. A Mexican license does not carry over everywhere. Texas DPS lists license reciprocity with a short list of countries, and Mexico is not on it. Arizona requires written and road tests for license holders from most countries, Mexico included, and sets the license to expire on the same date as your authorized presence document. California expects new residents who will drive to apply for a California license.
Car registration. If you bring a car, each state sets its own registration rules and deadlines. In California, a car registered elsewhere must be registered within 20 days of becoming a resident.
Housing without a U.S. credit history. You arrive with no U.S. credit score. Landlords may ask for a larger deposit, your offer letter or proof of income. Ask your employer whether it offers temporary housing while you search.
Bank account and payroll. Ask HR what the plant needs from you in the first week to set up payroll and direct deposit, and which documents to bring to open a bank account.
Health insurance start date. Ask when the employer's health coverage begins. Some plans start on day one; others start after a waiting period, and you will want to know which before you arrive.
What the Numbers Do Not Show
Texas
Manufacturing is spread across the state, from the petrochemical plants around Houston to the Dallas-Fort Worth area, San Antonio and the border cities. Distances are long and public transport is limited in most of the state, so a car is usually a necessity. Summers are hot and humid along the Gulf Coast and hot and dry in the west.
California
The highest prices of the three, above all for housing, and a wide range of plants, from food processing in the Central Valley to medical devices and electronics in the south. Coastal weather is mild, while inland valleys get very hot in summer. Commutes in the large metro areas can be long, so check the drive at the hours your shift starts and ends.
Arizona
Overall prices close to the national average, with manufacturing concentrated around Phoenix and Tucson, including semiconductors and commercial aerospace. If you grew up in Hermosillo or Mexicali, Phoenix summers will feel familiar. If you grew up in Toluca or Guadalajara, they will not.
Arizona and California both have large aerospace sectors. Commercial aerospace is a different matter from defense: roles in defense programs or under ITAR export controls are generally not open to engineers working on a TN. If a posting mentions either, ask about it before you invest time in the process.
Questions to Ask Once an Offer Names a City
An offer with a location on it turns a state comparison into a specific one. These questions are worth asking the employer, and yourself.
- How long is the commute from the neighborhoods where engineers at the plant usually live, at shift hours?
- Does the employer offer relocation support or temporary housing, and for how long?
- What does a one-bedroom apartment near the plant rent for today? Check current listings yourself.
- When does health coverage start, and what is the employee's share of the cost?
- Are there other engineers from Mexico at the site, or a Mexican professional community nearby?
The plant chooses the city. Use the state figures for a first read, then check the specific place: rent near the plant, the commute at shift hours, the state's license rules, and how state tax changes your take-home pay.
