The regional centre's administrative fee, the USCIS petition fees for the investor petition and later the removal-of-conditions petition, consular immigrant-visa fees, and professional fees for the source-of-funds work. The capital itself must remain at risk for the required period and is not a fee.
Separate the at-risk capital from everything that is a fee
Families sometimes blend the numbers into one figure, which hides the fact that some of the money is spent and some is invested. The administrative fee charged by the regional centre is spent; it does not count toward the qualifying amount and is not returned. The investment capital counts only if it is placed in the enterprise and at risk, and it may be returned only under the project's terms after the sustainment period.
USCIS fees are published on the fee schedule: the investor petition, the associated program fees, and after two years the petition to remove conditions. Consular processing carries immigrant-visa fees per person and medical examination costs. Professional fees vary with the complexity of the source-of-funds history; a gift from a parent with a long financial history adds work.
Cross-border tax planning is a further professional cost, and the advice may change the family's decision, so it belongs before the subscription, not after. Do not treat a project's projected return as an offset; the capital must be genuinely at risk, and promised returns are commercial claims, not immigration facts.
