Hi! My mom is an LPR who is petitioning for my dad to come here with my sister as derivative. After 29months finally the petition got approved (yay) question now is.. My mom lives with us, so will my dad and sister when they get here. With that being said, household will go up to 8. Question is; my mom does not meet the requirement for the uscis household guideline. She makes less which means I will have to be the co sponsor. My husband and I file our tax jointly, should be fine to send our tax
