Guys,

Me and my spouse we are willing to apply for green card lottery.

Now I have to apply as principle and add her as spouse in the application.

Can she apply again for her and add me as her spouse we can get higher chance to win the lottery, or we need to apply two applications each with one principle only? or one application for both of us?

Please help,

Dani

One application only. Multiple forms can result in disqualification.

This link will provide more information. It appears if both spouses qualify, then both can submit applications.
