An extension is a fresh assessment. The petitioner must show the U.S. entity has developed enough to support a primarily managerial or executive role, which is a question about what actually happened.
Month twelve is a decision, not a renewal
Hypothetical example: A new-office approval is granted for one year precisely because the entity is unproven. The extension asks whether the plan described in the original petition has become an operating business capable of supporting the role claimed. Evidence is retrospective: hires actually made, revenue actually earned, premises actually used, and duties the beneficiary actually performed.
A Selwyn company that spent the year with its manager personally doing sales and installation has a harder case than one that hired staff and can show the manager directing them, even if both are commercially healthy. The practical response is to treat the first year as an evidentiary period from day one, keeping records that will answer the question later. Total time in L-1A is capped at seven years, and the new-office year counts towards that ceiling.
