We had created elis account pay the GC fees approx 2 years back Now we are not able to login to ELIS and it does not send us forget password link to our registered email. Their website "If you paid the USCIS Immigrant Fee before August 31, 2015, you will no longer have access to your online account." Our was created before Aug, 31, 2015. So we are not able to login. I have 2 questions: 1. Can we keep ELIS Account number blank in the 751 form? 2. Is ELIS Account number and IOE # are same or different?
