US Immigration from Benin

Hello everyone. After submitting all the requirements and supporting documents to NVC, they all have been accepted except they left me this message:

IRENE does not meet the minimum income requirement to sponsor the intending immigrants for this case. The consular officer will make a decision regarding this requirement at the time of the interview. For more information, please visit https://www.uscis.gov/i-864p. To avoid delays, an additional Affidavit of Support Form I-864 for a joint sponsor may be submitted. FINANCIAL SPONSORSHIP RESPONSIBILITIES: Financial sponsors, joint sponsors, and applicants should be aware of responsibilities when signing an I-864 and the consequences for a sponsored immigrant's acceptance of federal means-tested public benefits. For more information visit https://nvc.state.gov/aos.

I m currently a soldier in US ARMY and my wife is the immigrant. After my researches I found out that as a service member my minimum annual income required is $17240 for a household size of 2. Except not my last 3 years income meet that requirement.
Here are my last 3 years of income:

In 2017: $19378 (Okay)

In 2018: $4939 (I have at during this year full time and didn t meet the requirements)

In 2019: $13401(I was already in the military and was deployed to Kuwait for 6 months and was getting paid with free tax. So in 2019 I only filed tax with the other remaining 6 months I was in states paying tax.)

NVC told me it s only the recent year income which is required.

My question is should We get a join sponsor or just go to the interview with my deployment order as support document event knowing we already provided it in the accepted documents.

Thanks!

Hi ! I filed March 2019 to remove conditions. My case was transfered to Potomac Jan 22 2020 due to work load. I haven't heard anything since then. Is anyone facing the same thing? Its been more than 3 months already. The waiting is not easy! Thanks
