Unfortunately, I am not a lawyer. I do know that my husband took vacation time off. Even when we were placed with children, we used vacation time. When he could he would take classes at night or weekends. Keep in mind that foster to adopt is a lot of hard work and you may want to consider whether you have the time available to put the effort in to do this. The classes are by far the least invasive part of fostering. You need to take them to their appointments (counseling, doctor, etc, and they have more than most kids), visiting time with parents, and need extra time and energy due to being separated from their natural parents. You may want to consider all of this before pursuing further. In other words, if you are unwilling to use vacation time for just the classes, you may need to consider this is not the right route for you. It's a huge sacrifice and not an easy one.
