If I cancel my US consulate (mexico) appointment, can i go back to the US using automatic visa revalidation?

Automatic visa revalidation is available for those who have visas (even if expired) in the passport, are traveling to Mexico or Canada for 30 days or less, hold a valid passport and legal nonimmigrant status, and reenter the U. S. at a port of entry. It is not available in cases where individuals choose to interview for a visa beforehand and are rejected. So if you are planning to use automatic visa revalidation, you can cancel the U. S. Consulate appointment unless you plan it so that you attempt to reenter first on automatic visa revalidation and if there is trouble, go to an appointment at the U. S. Consulate to try to obtain the visa. I do note that in past years there were reports of Customs and Border Protection officers sometimes giving people using this device a difficult time upon entry.
