Also, from what I know, you can start from Toho stage in Tokyo or Gekidan Shiki if you want to go back to Japan, as I've seen marvelous productions at Teigeki and Theater Creation (mostly musical theater). You do need a visa to work legally in the U.S., and are only able to join the Equity after being hired for a Broadway production or national tour. You can apply for O Visa, but it requires "a demonstrated record of extraordinary achievement." With Trump, however, you might want to stay in London for a while.
