Okay, we're getting a TON of posts about the TM.30 form <- and we're shutting them down as fast as we can post a link to Robert Lagas' excellent post explaining how it works.
To find out WHAT your particular immigration office requires as far as a TM.30. GO to your immigration office and ask.
I am not gonna leave threads open and have people who aren't using that immigration office chime in with what their immigration office does. There is so much disparity between then and how they handle those forms you need to check yourself.
