"This question is intended for residents or citizens who may be married to those who either are a nonresident spouse or a dual resident spouse. "
There are two issues with this.
First. It is a user interface problem. All it needs to do is ask the complete question about resident status, including being a citizen at the same time.
Current (something like this)
_ Spouse is a nonresident
_ Spouse is a dual resident
_ Spouse is a permanent resident
Fix by adding:
_ Spouse is a citizen.
That's it. Simple. The prior page has this selection, but it allows you to go to the next screen without answering the question. The other way to fix it is to ask the question on the prior page, and not allow to continue without answering.
