Premium processing buys a faster USCIS decision, not a better one. Whether it is worth the fee depends on how the U.S. operation is affected by a delayed arrival, which is a business judgement.
Price the delay, then decide
Hypothetical example: a Quispamsis managed-services firm has a client contract renewal that requires a named U.S.-based manager by a fixed date. The L-1A petition fee and the optional premium-processing fee are set by the USCIS fee schedule, Form G-1055, which should be checked at filing. Premium processing shortens USCIS adjudication time but does not shorten the time needed to gather the year-abroad evidence or fix the organization chart.
If the petition is filed with weak evidence to meet a deadline, a request for evidence will cost more time than the fee saved. The company should also budget for the L-2 filings for family members, credential translations if any records are in French only, and legal review. Comparing the fee to the contract's value usually answers the question quickly.
