in fact, I'm planning to return to China during the Christmas to attend a
conference there. so i'd like to extend
my mom's visa so that we'll be able to return together and i can take care
of my mom during the trip. is it a
good reason stated in the letter to apply for B2 extension? or should i just
state we need to tour some other
places of interest after we moved into a totally new place -from the eastern
to midwest (and that's true also).
thanks for your suggestions in advance.
