I got my DTV in March of this year. I did a 90 day report today and the immigration officer that helped me said that I shouldn't apply for a 6 month extension in September, and that I "should just leave and come back because it's easier, everyone with DTV does this."
Anyone have any experience with applying for the 6 month extension? 1900b for another 6 months sounds cheaper and easier than flying out and back in or doing a border run service every 6 months.
