good, at least that buys you time to get things sorted, so you can apply for the 90 day Non-O. Just go to your immigration office BEFORE you're going to apply for the Non-O 90 day visa and see what they say, believe me if there's an issue with that volunteer visa, they'll tell you about it right off. If don't say anything about it, you're good to go forward with the application
