Our plan is not to marry right away upon entry. Our marriage date is closer to the 90-day mark. Therefore, for the first 80+ days, she will not be on my insurance. In the meantime, we need options for insurance. A K-1 is a Non-Immigrant Visa, technically. So, how would travel insurance not work to cover my fiancée's needs until the marriage date? Other non-immigrant visas can cover a traveler to the US for 90 days. Why is this non-immigrant visa any different?
