So you got a 161; just lower your expectations on the law school, e.g., from Harvard to a state school.
In addition, in the application, talk about your work experience and how it has given you perspective that would enhance your ability to study and practice law.
Try to pick a law school that is in the same or nearby phyical location as where you want to practise because there will be a better network of alumni attorneys in hiring positions there (this matters).
I guess I'm assuming you aren't planning on law school in SG as they're all in the same general location
