Worth remembering that the US majors seems to still have the crazy requirement of a degree to even have a chance of applying. May want to consider that along the line at some point. Doesn’t have to be a good degree, bachelors in Brazilian history from the university of Bumble-Nowhere is absolutely adequate.
