US Immigration from Japan

I want to know how long does it take until the NVC set interview after documents qualified (I'm not asking when's the date of interview ) I'm asking just how long until they send you email about your interview date

My fiance and I applied for our i-129f in late October. Due to Japan's restrictions on mail and our inability to visit each other during COVID we were forced to send our application with photocopies of original signed documents. We read this USCIS article (https://www.uscis.gov/news/alerts/uscis-announces-flexibility-in-submitting-required-signatures-during-covid-19-national-emergency) which says that the USCIS is temporarily accepting photocopies of signed docs due to covid restrictions; however, this article was released nearly a year ago, and updated in may of 2020. As of yet there has been no updates on if this is still acceptable, and it has proven to be nearly impossible to speak to anyone at USCIS or even USPS on restriction updates. Now that my fiance and I are preparing for interview time and the later half of this process we are wondering if it will still be acceptable to use photocopies of original signed documents to complete our journey.

Please let us know if you are in a similar boat, or have any insight on this situation that may help us or anyone else out.

Does anyone know if there are plans for the i-751 form to be updated (new version) or for the filing fee to change/increase between now and the end of March? Thanks!

I am nearing 2 months now with no NOA1 and they signed for my package upon receiving it. I am desperate to get this NOA1 as I have not seen my fianc in 1.5 years. From what I understand people who are in the same boat and have called only get the runaround. What recourse do we have if any if calling does nothing?

Is the evaluation of equivalency just required for university, or is it needed for high school as well?

Is it ok to just list the college info on the I-944 or should high school be listed as well?
