my brother was barred for five years for working on tourist visa

I assume that your brother had a problem on entry which caused the 5 year bar. After the 5 years, he may be able to apply for another tourist visa, and whether he gets it will depend on the discretion of the American consulate or embassy officer. If he is able to show that he has good ties and bonds with the home country and makes a good impression, there is a good chance that he may be able to obtain the tourist visa.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
