If you have to leave the country you are in and go back to the usa. How long does it take to prove domicile inside usa?

My spouse and I live in his home country for 4 years. we have a small child with each other. his interview just recently passed and he was given a 221g white slip. In the interview they told my spouse that they need to see our plans for usa. they want me to fill out job applications and submit them to them and show Domicile. Is this a normal thing? Does everyone who resides outside of country with spouse have to prove domicile? What should we do or expect about this? we are fixing to send what papers they requested next week, How long will it take for them to give us an answer or accept it? the woman said we are done with the embassy and handed back his passport and told him to return the papers with passport through mail.
