The answer to this question depends on the factual basis for your mother's previous B-2 visa denials Unless the consular officer denied her B-2 on criminal, fraud, health or such other grounds, she should not have any problem in getting her immigrant visa approved if you decide to file her petition. because, the requirements for approval of a B-2 visa is different from what you need to prove to obtain an I-130 petition. But before you file her I-130 petition, you should, if possible review any and all documents she may have submitted to the consulate in her previous B-2 visa applications so that when you file her I-130 petition, you do not get tripped up by inconsistent or contradictory information already on her file with the consulate.
