For an Immigration law firm, is broad targeting the way to go?

For my Immigration law firm, I have been using Facebook ads, and I have come across discussions about targeting. For month1, I have run all 3 ad sets broad, cut down based on cost per lead and calls booked.

My ideal customer profile pretty much doesn't exist in Facebook's interests; the max I can do is newlywed, either 3 or 6 months, and the audience available is less than 100k, which is expected.

What's the way to go from here?
