Question after checking K-1 Visa Guide on this site

[Trymester3 6]

About 10 days ago, I received notice that our I-129F was approved.

So, I was directed to check the K-1 Visa Guide and have a few questions:

-It suggests that I send my beneficiary a whole bunch of things so that she may have them ready for her interview, but I plan on attending the interview (and probably getting to Japan a week or 2 before the interview), shouldn't I just bring them with me to ensure their arrival?

-It mentions the Affidavit of Support should be sent. I thought this was something that needed to be presented after the marriage had already happened (I could've swore I read that on here). Something along the lines of, after the marriage happens, she will need for me to provide an affidavit of support before she is allowed to live in the US as a resident. Am I wrong? Is the K-1 Visa guide accurate in that she will need to present the affidavit of support for the interview? I plan on having my mother's finances presented as support, because even though I make enough for us to live, it doesn't look so good on paper as I work as an independent contractor.

She will need to present an I-134 completed by you and any other sponsor at the interview.

When going through the Adjustment of Status process, you and any joint sponsor will need to complete and submit an I-864.

IF you are going to be there before the interview then why not just bring the documents and save the mailing costs. In my case, I didn't send most of the physical documents to my beneficiary. I scanned all of the documents that didn't require an original signature and transferred them to her smartphone's memory {encrypted}. The items that required an original signature I did have to post.

Just to expand a little on the above answer.

For the USEM interview the beneficiary will need separate I-134 forms completely filled out AND supporting documents for the primary sponsor and each co-/joint sponsor. {i.e. at least two I-134 forms and supporting documents} and each must bear an original signature. {no faxed, emailed, photocopied, etc. signatures}

For the AOS process the beneficiary will need separate I-864 forms completely filled out AND supporting documents for the primary sponsor and each co-/joint sponsor. {i.e. at least two I-864 forms and supporting documents} and each must bear an original signature. {no faxed, emailed, photocopied, etc. signatures}

Thank you so much folks, I will look at I-134 forms now and see how easy or difficult it is to get the supporting documents. Thanks.
