Hey US_visa
you have wrong Info
Automatic validation rule is still there.
In an attempt to enhance border security, and ensure that only foreign nationals eligible to enter the U.S. are allowed entry, effective April 1, 2002, foreign nationals who have applied for and been refused a visa while outside the U.S. are prohibited from returning to the U.S., even if they are in possession of a valid I-94. The previous regulation allowed foreign nationals whose visas had expired but their I-94 remained valid to re-enter the U.S. without obtaining a new visa. This change in the regulations means that in the case where a TCN is denied a visa at the Border Post, the TCN must return to their home country to get a visa before they can re-enter the U.S.
It is essential for foreign nationals to understand the risks that are now involved in applying for a U.S. visa in Canada or Mexico. If the visa application is approved, there is no problem.However, if the visa is denied, you cannot return to the U.S. until you have obtained a new visa in your home country! Generally, the most successful visa applications are those from individuals who are applying for a visa in a category for which they have been previously issued a visa, however, the risks have certainly increased in the recent past.
If you do not apply for a visa and are not a part of the state terrorism sponsor countries, you can come back to USA from canada under the contious territory rule
