So have you been filing US taxes though these last 3 years? On the I-864 what did you put for your 2022 current income and 2021, 2020 and 2019.
Those fields should be %0 and a statement this is foreign income. If you didn't file you also need to state why you didn't file taxes. If you were required you will have to file before you go any further. Matters not you have a joint sponsor you are the petitioner and things are required from you.
