US Immigration from Japan

Apologies for the second thread, but I feel this is a distinct enough topic to warrant its own discussion.

My spouse and I did not have a wedding ceremony or purchase engagement rings. It s also not something that we plan to do, though we may purchase rings in the future, it s not a priority at all. There was no proposal or any event like that, we simply discussed that we wanted to get married after having been together already for many years.

We have plenty of other evidence of a relationship. Joint bank accounts, life insurance for both of us, joint utilities bills, lease, health insurance, etc.

Is this a concern for the AOS interview?

I m asking because some of the original material (documents, etc) submitted with the K1 package is in my spouse s country and not with us, and I m not sure if we will be able to obtain that in time for the AOS interview. Will this be a problem?

The AOS interview letter only mentions bringing originals from the AOS application (or at least, that is what it seems to imply).

Should we be concerned and be rushing to obtain originals?
