These days your computer tattles to your search engine where you are. The search engines put you in a pigeon hole by reading your ip address, and here we are in the pigeon hole called Mexico. This is why when you try to use Google your computer forces you to use Google.mx. The Mexican version of Google, with nearly everything in Spanish.
So you want to use good old Google.USA. but your computer won’t let you.

If you’re not in Mexico yet, set Google as your home page and it will hold GoogleUSA in it for you.

But if you’re already down here Google will no longer allow that. You can delete .mx until you’re blue in the face and you can’t get it to go to USA.

Here’s all you do:

Enter www.google.com/ncr

It’s that simple.

Usually it works. If it doesn’t, try again in a little while.
