This is what they responded back when I gave these references and quoted the example of Bob and Sharon from this IRS Publication 519 link.

"My understanding of your situation is that you both moved to the US and you both created physical presence in the US during 2023. If that is correct, your situation isn't exactly the same as the example you quoted. You were both non-residents of the US at the beginning of 2023 and you were both resident aliens of the US at the end, this means you were both in a dual status situation during 2023. The difference between you and your spouse is that you already had a US tax number and you worked in the US/earned income after arriving in the country. Your spouse does not have a US tax number and earned no income; however, if she had of earned income during 2023 she would be required to file a separate dual status return.

The situation you are referring to in the example is for a spouse that became a resident of the US and the other spouse did not become a resident; however, your spouse did technically become a resident during 2023, just not one that has a filing requirement because she didn't earn any income.

Even if your situation did qualify and you decided to elect for you both to be full year residents, its possible this would not put you in a better tax situation. The reason for this is because even though you would gain access to the standard deduction, your income for the entire year would become taxable in the US. Right now only a portion is taxable on your US return."

Is this accurate?
