1) A website (http://www.immihelp.com/visas/extend.html) mentioned that there is no need to send the original I-94. Here is the text:
Even though the form says you must send original I-94, you must also send the photocopy of I-94 form. Do NOT send the original. You are not required to send the original. If you sent the original by mistake, and if you need it back, you can file form G-884 with USCIS. G-884 is not available on. You have to request it by mail.
2) Some one told me I must send the original I-94.
Which one is ture?
Thank you for input.
