Dad had interview appointment at 8:30pm on 10/16/2007. He had been rejected
by 5 times. This time he prepared for it very well especially he brought all
of original documents and pictures. The officer asked a couple of questions
and looked at his bank statements and pictures. Then he passed this time.
My mother will try it next year after my dad goes back.
Thanks for all of information from MITBBS. Wish everybody have good luck!
