Not automatically. The rules distinguish continuity from qualifying time: brief business or pleasure trips may preserve continuity, but U.S. time does not count toward the foreign-employment year.
Have the actual history calculated
Provide dates, activities, employer and status information for individual assessment. Do not infer eligibility from an employment anniversary alone. The applicable period and other L requirements still need review.
Notice that nobody in the room is the decision-maker on this point. The applicant supplies dates and activities, the employer supplies employment records, the adviser applies the rules, and an officer reaches the conclusion. Trouble starts when one of those parties quietly takes on another's job, most often an applicant who decides for himself that a short trip does not count and therefore leaves it out.
Give the full history instead: for each U.S. period, the entry and exit dates, the purpose, the employer at the time, and the status held. The rules treat continuity and qualifying time as two separate questions, so a brief business or pleasure trip may leave continuity intact while those same days still do not count toward the required year abroad.
Both answers come out of the same disclosed history, and only one of them is sensitive to how the trip is characterised. Where records are incomplete, identify which period is uncertain rather than rounding it, because the qualifying-year finding is only as reliable as the weakest date underneath it.
