Assuming that you are a US citizen/ resident and because your husband was admitted into the country under a visa ( K-1), he would be treated as a non-resident alien till the issuance of the green card ( chnage of status). But being a non-resident alien does not take away the requirement to have health insurance under the ACA. I am assuming that he was working in the USA while awaiting the green card-- did his employer not provide health insurance or was he self-employed ?
