I'm a bit confused. I extended my non-O visa last month. At the time I switched the basis for my status from trailing spouse to 800K deposit. The officer gave me a new 90 day reporting slip, good through April, starting from my new extension, and pulled out the old extension through February 28 from my passport. He said he could do that since I changed my status.

The other day I got an email telling me to make sure that I do my 90 day extension by February 28! What should I believe?
