Here's US embassy in Thailand's further information/instructions on K-1: https://th.usembassy.gov/visas/immigrant-visas/packets/

Hope she finds them useful!

When it first shows as Ready, it means your case file has just been received by your fiancée's local embassy. 
 
Not sure with the BKK embassy but some embassies require the applicant to schedule the interview him/herself after receiving Packet 3 and submitting DS-160 online. 
 
Right now she'll need to hang tight to hear from the embassy. Could be postal mail or email. Depends on the embassy.

Signed letter by bank personnel

re the bank statements - is this an actual letter from the bank or just a prinout of your money in and out (transactions) over a period? some people say it has to be a letter signed by the bank manager while some others say just the usual monthly statements will do. i'm confused, please help! thanks! =)

Hey thank you both for your quick replies, it makes sense to aim about 30 days from the interview date

They might accept the documents no problem but it might be better to forward your fiance the documents dated closer to the interview date. That way it's most up to date. Don't forget the I-134 and tax transcripts by the way

I aimed for about 30 days a head of time, that way everything was pretty recent.
 
Depending on how the scheduling works for interview in Thailand, as soon as it is scheduled you could definately send the documents over.

I suggest taking a step back and a deep breath. There's a lot more ahead in your immigration journey, so worrying too much won't be good for you or your fiance.
 
They may not really care and just see it on the G-325A. If not, they'll issue an RFE for it and you can provide a revised form at that time. RFEs generally only add a few weeks to the process (Mine took exactly 14 calendar days recently).
 
You generally cannot provide additional evidence to an I-129F case until you receive an RFE. I tried to do so myself but they wouldn't accept it until they issued the RFE (for the exact thing I tried to send them).
