Effective March 1, 2012, the U.S. Embassy in Lisbon, Portugal will no longer be processing immigrant visa applications to the United States. Instead, individuals will be directed to apply for immigrant processing through the U.S. Embassy in Paris. This change is due to the “relatively low demand” for immigrant visas in Portugal.
Not to be caught up in the confusion, nonimmigrant visa applications are still being processed in Lisbon. The U.S. Consulate’s webpage has more information.
