The base filing structure follows the standard USCIS fee schedule; additional cost usually comes from the extra evidence-gathering the continuity issue requires, not from a separate government charge.
Expect evidentiary cost, not a distinct continuity fee
There is no separate USCIS fee specifically tied to explaining a layoff or continuity gap; the petition still follows the standard Form I-129 fee structure under the current USCIS fee schedule, Form G-1055, which should be checked directly since figures change. Where the practical cost tends to rise is in the time and documentation needed to reconstruct a clean twelve-month record around the interruption: pulling historical payroll records, drafting an explanatory letter, and confirming organizational charts from before and after the layoff all take longer than assembling a straightforward, uninterrupted employment history would. Employers planning a transfer around an employee whose record includes a gap should budget the additional preparation time as the real cost driver, rather than expecting a separate line-item government fee for the continuity issue itself.
