Form I-864 FAQs

Can a joint sponsor be used when income is insufficient?+

Many cases allow a qualifying joint sponsor, but the petitioner generally still submits a separate I-864.

Can foreign income be counted?+

The analysis turns on whether income continues after immigration and whether U.S. domicile exists or will be reestablished.

Can this worksheet be filed directly?+

No. This is a I-864 preparation worksheet. File only through the current official form or system.

Should AI translate a person's name?+

No. Use the existing passport or official-record spelling. Names and identification numbers are never sent to AI.

Why are fees and addresses not hardcoded?+

Agencies change fees, filing channels, and addresses. Verify them again on the actual filing date.
