Hola Brandon

I am not sure what your question is but I imagine you are wondering whether we use ser or estar in this sentence:

My husband is from Costa Rica

For this we use "ser de" (to be from):

If you want to say for example My husband is in Costa Rica." then we use "estar en...":

I hope this clarified it for you (if that was the actual doubt)

Here are two lessons explaining this:

Estar for location 

Ser for origin

Saludos
