I use the same method as you , however Iโm on O-A extensions , and renewed mine last October, just before the health insurance came into play .. so come Sept / Oct this year I will need it when I come to extend this time , Iโd rather not have it though ... ๐คท๐ป
You mean this ... I had to go to immigration 90:days after I got my last 0-A extension to show I still had the 800k .. this form shows what you need to bring
