Фирма в США

Нет, не подойдут. Иметь лишь компанию недостаточно. Нужно Вам дополнительно иметь ПМЖ в старанах перечисленных ниже.

Ниже я скопировал часть термсов Кикстартера.

Kickstarter is open to backers all over the world.

Meanwhile, project creation is currently available to individuals in the US, UK, Canada, Australia, New Zealand, the Netherlands, Denmark, Ireland, Norway, Sweden and Germany who meet the requirements below.

—You are 18 years of age or older.*

—You are a permanent resident of the country that you're creating a project in, either in your own name or on behalf of a registered legal entity.

—You have an address, bank account, and government-issued ID based in the country that you're creating a project in.**

—You have a major credit or debit card.

*Parents and teachers can launch projects in collaboration with children under 18 only if the adult registers for the Kickstarter and payments accounts and is in charge of running the project itself.

**Citizens of the E.U. are welcome to use a government-issued ID from any E.U. country (such as an E.U. passport, etc).
