If you want to stay in the US, then it never hurts to act with purpose. There are plenty of non-foreigners that go to American law schools and that struggle to find jobs, and plenty that do not. If you have a skill set that other companies want, they will sponsor your visa. What kind of law are you interested in? It might not hurt to make an appointment with a career counselor at the law school to visit about some of the challenges you might be facing as a foreign student. What if you went to law school in your country and then studied abroad for a semester, or if you got a law degree in your country and then went to the US for a LLM (master's of law?). If you want to live and work in the US, then get the education you need to do so and work towards that goal. If you're not quite ready to commit, then perhaps exploring other options will make you more comfortable when it's time to decide.
