About
Aurora Access is a New York–based advisory practice focused on the moments when businesses cross borders: entering the US, filing correctly once they are here, and expanding abroad from the US.
Every engagement is led personally by our founder, Nobue Sato Block, CPA. Clients work directly with an experienced professional, in English or Japanese, rather than being passed between teams.
We act as a single point of coordination in the US — working alongside your headquarters, banks, legal counsel and other advisors.
