Hello all,
 
I'm petitioning my fiance for a K-1 visa and she has her interview scheduled this Thursday.  When going through our final checklist last week, she realized that we must have misplaced our original copy of my signed I-134 form I had completed as part of our Evidence of Support.  I immediately filled out a new copy on Friday and sent it via DHL to my fiance to arrive at the earlist possible opportunity, which is unfrotunately the day AFTER her interview.  So not I'm wondering if it would be best for her to attend the interview THursday as scheduled, or try and reschedule to a later time.  
 
If she proceeds with the interview Thursday, this is what she will have available as evidence:
 
Copy of I-134 form with digital signature only Copy of my U.S. Passport to indicate U.S. status Copy of final 2020 paystub with Year-end totals Copy of first 2021 paystub Copy of 2019 W2 (2020 is not available yet) Copy of 2019 Federal Tax Return December 2020 Checking Account Statement December 2020 Savings Account Statement December 2020 Health Savings Account Statement December 2020 Roth IRA Statement December 2020 401k Statement December 2020 non-retirement Brokerage Statements Screenshot of U.S. Treasury website showing holdings of U.S. series I and series EE bonds (no statements are available on the TreasuryDirect webpage)  
In addition to whether it would be better to proceed Thursday or postpone.........are there any other documents that may be suggested?  I saw some individuals have included letters from their emplyoer which we did not do, however I could contact my comapny's HR department on Monday to get something quick if necessary.
 
Thanks in advance everyone.
