that mean wait for interview 2 to 6 months

@kaur kaur what?? if there is a request for evidence it means something is missing. The questuon isnt quite clear but everyones wait time from NVC isnt the same.

@E R The income reported as stated on form I-864, I-864A is insufficient to overcome the public charge grounds of inadmissibility for visa issuance. To avoid delays, an additional Affidavit of Support Form I-864 from a joint sponsor may be submitted. For more information visit https://nvc.state.gov/aos and https://www.uscis.gov/i-864p. A consular officer will decide if you meet these requirements at the time of the interview. Note: You, as the sponsor, and any other sponsors household members and joint sponsors, must provide updated or additional evidence for the applicant to present at the time of their interview such as: * Other income * Assets * Proof of current employment Note: You submitted documentation to the National Visa Center through the Consular Electronic Application Center CEAC. You can continue to upload documents to CEAC up until the date of your visa interview.

this was the message

@yukta kesar ah ok so you need a joint sponsor which means that person needs to sign an affidavit of support and provide their tax transcripts. Both your incomes combined should be more than the poverty limit to overcome any public charge. Ask a relative or close friend.

@E R i already did have joint sponsor and household member as well my brother and sister in law still i got this message
