Separate the proposed share purchase and corporate advice from government charges, immigration services and document preparation. They are different commitments even if one adviser introduces the opportunity.
Ask for separate explanations of the work
Clarify what an immigration assessment includes and what requires corporate or financial review. Confirm the official charges for the selected procedure. If translations or credential evaluations are suggested, ask which requirement they address. Buying shares or spending more on a transaction does not make an otherwise ineligible professional role qualify.
If a foreign degree is presented from an institution outside Canada, Mexico and the United States, the reliable evaluation rule applies to that degree; do not convert the category itself into a universal degree requirement. The larger cost of the petition route is preparation: assembling the support letter, degree evaluation, organizational documents and any explanation of a staffing structure takes professional hours that the border route mostly avoids. Government fees differ between a port-of-entry application and an I-129 petition, and premium processing is an optional extra with its own charge, so confirm each figure from the current USCIS fee schedule rather than an older quote.
