How do I answer these questions,

Is your spouse immigrating to the U.S. with you?

I mean, my spouse is coming to the U.S. with me but she is a U.S. citizen, so she won't be immigrating. Answer NO?

Have you ever sought to obtain or assist others to obtain a visa, entry into the United States, or any other United States immigration benefit by fraud or willful misrepresentation or other unlawful means?

EWI, do I answer yes or no?

Have you ever been unlawfully present, overstayed the amount of time granted by an immigration offical or otherwise violated the terms of a U.S. visa?

This is a question referring to visa overstay? I mean I had been unlawfully present before DACA, do I answer yes or no?

Do you have documentation to establish that you have received vaccinations in accordance with U.S. law?

All my vaccination records are lost, do I answer no and explain in the comment section?
