The 3-Year and 10-Year Bars
Less than 180 days of unlawful presence:
Generally no bar triggered upon departure. You may be able to proceed to consular processing without a waiver (depending on other factors).
180 days to 1 year of unlawful presence:
If you leave the U.S., a 3-year bar from re-entering is triggered. A waiver may be required.
More than 1 year of unlawful presence:
If you leave the U.S., a 10-year bar is triggered. A waiver (I-601 or I-601A) is required before you can return.
CRITICAL: Do not leave the United States without first consulting an immigration attorney. Departure may trigger bars that could take years to resolve.
