Can a us citizen fix papers for spouse mother and siblings at once?

Yes, a U.S. citizen can potentially sponsor their spouse, mother, and siblings for Immigration simultaneously, but the process can vary based on each individual's eligibility and the visa categories involved. The U.S. citizen would need to file separate petitions (Form I-130) for each family member, as each one is treated individually under immigration laws. Additionally, processing times and visa availability can differ for each relative, particularly for siblings, who face longer waiting periods. It's advisable to consult with an immigration attorney for personalized guidance.
