In terms of the number of children included in the application, there is a minimum impact on costs, only more medicals and documents etc. Therefore not significant.
What’s the best way to get permanent residency in New Zealand if I move with family from the U.S. during the pandemic?
I have a large family and I want to permanently relocate to the New Zealand. How does the number of dependents impact one's investor visa application, especially in terms of costs?
Being able to move during the pandemic is not likely. Visa processing for people that are currently offshore is on hold, with very limited exceptions, for example, for healthcare-related jobs and some other very specific types of jobs. Investor visa applications are processed, but not approved until after the border closure measures have been lifted. The skilled migrant program is closed until April 2021. The costs of an investor visa application are not affected by the number of dependents that are on the application. It is a fixed fee. However, dependents are limited to partner/spouse and children. You cannot include extended family members (or parents).
You can include your partner and dependent children up til the age of 24, who are single and dependent on you for financial support in your investor visa application. The number of dependents included in the application does not cause any impact in terms of visa application costs because you only have to pay one application fee and an immigration levy, irrespective of the people included in your investor visa application.
