why would he apply for the lottery if he already has a greencard?????? Or does he want to apply again so that his wife would get a greencard this time?? If that's the case, his wife has to apply. I suppose if he would be the principal applicant again, and he would win, his wife's visa would be dependent on his visa, but he cannot get a new immigrant visa if he already is a permanent resident, therefore his wife could not get a visa either. This thought is based on logical thinking, however, the legal reality might be different.
