Can I sponsor my mom if I have a permanent job but I am still considered below poverty?

Generally a U.S. citizen (whether a citizen through naturalization or through birth) may succeed in sponsoring a parent for immigration benefits in the Immediate Relative visa category. If the U.S. citizen does not have sufficient documentable income to meet the requirements, it may be necessary to include a Joint Sponsor in the application process. Generally a joint sponsor may be any U.S. citizen or Permanent Resident who has sufficient documentable income and who is willing to assume the responsibilities contemplated in the Affidavit of Support. Of course, there are many additional details that determine immigration eligibility. It would be wise for you and your mother to consult with an immigration attorney who, after learning all of the relevant information, could advise about eligibilities, options and strategies to attain your goals, and who then could offer legal representation in the often complex application process.
