H4 EAD USCIS and DHS H4 EAD mean the same thing. You have to send a postal application to the USCIS lockbox address.

USCIS forwards your H4 EAD application internally to other centers from Dallas or Phoenix themselves. You do not need to worry about it.

How to find out the H4 EAD filing address:

  1. Filing i765 EAD alone: You should use H1B’s most recent approval notice written on form i797. Keep reading this article to find the address.
  2. Filing i765 EAD with i539: You should send the i765 along with i539 at the USCIS address where you are sending form i539. Form i539 filing address can be found on the USCIS website.
  3. Filing i765 EAD with i539 and/or i129: Send all of them to the USCIS filing address for form i129.

You can use this app to fill the form, validate all and make sure the form is not rejected or an RFE is sent by USCIS:

H1B Receipt Number Starts with IOE?

USCIS has recently started generating H1B receipt numbers using their e-filing with receipt numbers that start with IOE or MCT.

In this case, the actual service center name is written at the bottom of the receipt.

H4 EAD applications are sent to other USCIS service centers after sorting through the lockbox addresses. You will get an H4 EAD receipt number separately from the final service center.

    My I797 for I-129 starts with IOE and at bottom it says Nebraska service center. I am confused where should I send documents, since USCIS has updated their Direct filing instructions to include IOE as well.

    IOE- Phoenix lockbox
    LIN(Nebraska) - Dallas lockbox

    Can you please advise.

  4. syaThakur

    I ended up sending at the center with I-129. (Nebraska for me, hence sent to Dallas Lockbox)
    My I-765 was then sent with receipt from Vermont.

  5. bathula8
