good evening, my question is as follow: I am a US citizen and had petition my brother in june 2002, at that time my brother enter the united states with a visitor visa but overstay, his I-94 did not expire until december of 2002, I recently receive a package from national visa center explaining the process and that his visa is available, my question is now that he is the united states will he be able to adjust status, should I continue with this process, and if there is a waiver that he could apply in order for him to stay in the united states, he currently is married and has US citizen kids...what are his chances of him adjusting status in the united states.
thank you for your time on this matter
