How can I receive my dues/balance pay from previous job while being on H4 visa

If the payment will be given in the same tax year in which you held the L-2 visa status and valid EAD, the payment for your past job would likely not be an issue. If in another tax year, and assuming that there is some proof of your payment existent, the company could perhaps provide an explanation as to what period of services the payment covers. If the company pays directly into your account in India, there would of course be no record of any payment in the States. If you are concerned about the legality of such an arrangement tax wise, you could perhaps seek the advice of an accountant or tax lawyer.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.
