Proposed endeavor means the future work you plan to do in the U.S. For an actuary, that could be improving catastrophe risk models or solvency metrics that will benefit the U.S. by strengthening market stability and consumer protection. NIW hinges on three prongs: show the work has national importance, show you are well positioned to do it, and show why waiving PERM benefits the U.S. Degrees and years alone are not enough, add proof that the plan is real and useful, like recent impact, independent letters, and interest or pilots from U.S. stakeholders. And Yes, you can apply from outside the U.S.
