Can I travel from America to Mexico on a road trip?

Hi, thanks for your help, in advance. I've browsed other questions, but none seem to ask exactly what I'm after. My American friends have invited me on a road trip to Mexico from the States. I was just curious as to whether I would have a hard time crossing the border into Mexico with them? Or is the visa waiver and having a British passport good enough?

I would be flying into Iowa in the states, then driving down to Mexico, and back.

Thanks for your help. Much appreciated. I really want to go on this; it's the stuff memories are made of, but if it's too difficult to get in/out of Mexico, there seems little point.

Yes you can drive directly from the US into Mexico. The border between these 2 countries stretches from the Pacific coast in California through Arizona, New Mexico to Texas. Many residents from both sides commute daily to go to work, school, visit family..... so crossing over is very easy. Of course, going into Mexico is much faster than coming back into the US because the US border patrol has much stricter control. At many border customs, you just drive right through into Mexico without anyone stopping you to check your i.d.

longliveabcdefg's answer appears to ignore the fact that you are not a US citizen.

The website of the Consular Section of the Mexican Embassy in London indicates that UK citizens can visit without a visa for up to 180 days, provided that your passport is valid for at least 6 months after you leave Mexico, but it does mention the need to get a blue tourist card (FMTTV migration form) from airlines on direct flights to Mexico and at ports of entry to Mexico - I don't know if that includes land border crossings, and I would suggest you contact the Consulate on 020 7907 9442 to get a definitive statement of the situation.

Of course, once you've been into Mexico, the other question is whether the US Immigration will cause you problems trying to re-enter the US overland. If you are entering the US by land then you must have a completed form I-94W, issued by the immigration authorities at the port of entry, and pay a $6 fee in cash.

You don't need a visa, you just need to fill in a thing called an FMT tourist card at the border. If you're hiring a car though you won't be able to take that into Mexico.
