I would suggest that first you become a foster parent. This will get you used to taking in strange kids and some of whom have real problems. Some of these problems, even if known to others, are not mentioned to the adoptive parents, so it's best to get used to our own kids in need. There are a lot of them in America and these are pushed aside for kids from other countries in this world.
In doing this you would have your home inspected, your and your husbands' lives inspected in depth, your financial affairs known to them, changes forced to be made in your house, and in the end it's far easier to change your mind with foster kids than with actual kids who will make you lose your heart when they call you Mom.
I know folks who have done both, became foster parents and then adopted children they didn't want anyone else to abuse because they fell in love with some of the damaged ones. Marvelous familes, all of them, and the world needs more of that kind.
