L-1 Foreign Employment Timing
L-1 Three Year Lookback Period
How USCIS determines the three year period in which the beneficiary must complete the qualifying one year of foreign employment.
Direct answer
What the governing framework requires
The one year of qualifying foreign employment generally must fall within the three years preceding the relevant initial L-1 filing or admission analysis. USCIS policy also recognizes adjustments to the three year period in specified circumstances involving qualifying employment in the United States.
01 · General Rule
The qualifying year must be recent enough for L-1
L-1 does not allow a beneficiary to rely indefinitely on qualifying foreign employment from the distant past.
The one continuous year must fall within the applicable three year period.
02 · Initial Petition
The relevant calculation should be made before the initial L-1 petition
USCIS policy explains how the three year period is measured for initial L classification.
A detailed chronology should identify both qualifying foreign employment and intervening U.S. periods.
03 · Qualifying U.S. Employment
Certain U.S. employment for the qualifying organization can adjust the period
USCIS policy recognizes that qualifying employment in the United States for the related organization can affect the three year calculation.
That rule should not be expanded to every period a beneficiary happened to spend in the United States.
04 · Other U.S. Status
Time in an unrelated U.S. status may produce a different result
A person who spends substantial time in the United States for reasons unrelated to qualifying employment should not assume the lookback window is automatically extended.
The exact status, employer, dates, and activity should be reviewed.
05 · Travel History
Passport and I-94 records can be important to reconstructing the window
Travel can affect both the continuity of foreign employment and the amount of foreign time that actually counts.
A reliable chronology is particularly important where the beneficiary traveled frequently.

Frequently asked questions
What is the L-1 three year lookback?
It is the period in which the beneficiary generally must have completed the required one continuous year of qualifying foreign employment.
Can very old foreign employment qualify?
Generally it must fall within the applicable three year period, subject to the specific USCIS timing rules.
Can U.S. employment extend the three year period?
Qualifying U.S. employment for the related organization can affect the calculation under USCIS policy.
Does any U.S. stay extend the lookback?
No. The reason for the U.S. stay and whether the beneficiary worked for the qualifying organization matter.
Why does travel history matter?
U.S. periods can affect both the one year count and the three year lookback calculation.
