Getting Married to My Fiance in The US

Hello,

I am looking for some advice on getting my soon to be wife (again) here.

Some background information that may or may not be pertinent.

Her and I have been together since 2016, got married briefly in 2017 when we were living in Japan. We divorced due to some particular circumstances that were going to cause us to be separated for an extended period of time (nothing of the criminal nature, we both have clean records) and we wanted to ensure that if anything were to happen during that time that we would both be able to move forward in separate directions if our situations caused us to do so.

Now that that is out of the way, we have remained together since the separation and would like to proceed to get married again as both of our situations (financial and otherwise) are much more in line with what we had originally planned.

I filed the paperwork for her to obtain a tourist visa to come to the United States while we were in Japan. There was no issue and it is still valid.

She will be coming to visit soon and will be spending several months here (within the limits of her visa of course) so we can make some future plans that are in line with her cultural values. What we would like to do is to initially get married while she is here (from what I have seen as to an immigration standpoint is that this is fine so long as she absolutely intends to return to Indonesia after, which is 100% the case) and then after her return to Indonesia, file an I-130 and then an I-129 once I have received the I-797C so that she can come here on a non-immigrant K3 visa while the I-130 is processing. The reason for this is that we do not want to spend more time apart waiting the 6-8 months for a fiance visa to get processed, as we have been together for two years and separated for one already.

I have done a bit of reading and I haven't really been able to acquire much information on this, other than pretty much seeing everything discouraging the attempt at a change of status from a tourist visa while still in the United States. We are perfectly fine not doing that as it is not our plan. We will respect and follow the law as it is written.

My first question is:

Has anyone here gotten married on a tourist visa, returned to Indonesia, and then filed the I-130/I-129 to return to the United States to be with their spouse while the I-130 is processing and what hoops if any, were there to jump through?

My second question is:

What paperwork will she need from Indonesia to be able to get married here in the US aside from our divorce certificate which we both have?

As a side note, we have proof of our relationship over the past two years, pictures, conversations, divorce certificate (maybe not the best proof with that, but we may need it I'm guessing), and also, both of our families flew to Japan and met and spent time together which we also have proof of.
