The cost plan should distinguish corporate preparation, government charges, document work, travel, and separately scoped professional services.
Budget for facts that may change
List costs by owner: the employer may pay corporate-record retrieval and petition work, while a household may bear passport renewals, translations, travel, or school-related expenses. Hypothetical example: A new US operation leases space before the transfer is decided. The lease can be evidence, but its cost does not guarantee petition approval or make every later expense reimbursable.
Confirm current government fees from the relevant authority immediately before filing, since figures and payment methods can change. Leave room for document certifications, courier delivery, and a response to a government request if one arises. Do not label every business expense an immigration expense; keep books accurate.
A written scope should specify what review is included and what later change, extension, or new-office follow-up would require further assessment. Use a written assumptions list with a date beside every estimate. Confirm official charges shortly before payment and ask providers what their scope excludes.
Do not treat money already spent on a commercial plan as proof that an immigration category fits. A reserve for changed facts is prudent, but it should never be described as a way to purchase approval. For this l1a review, keep that conclusion tied to the documents actually available.
Confirm the current procedure before relying on an earlier file or informal description.
