<p>I'd really divide it into three groups: group one: direct from UG; group 2: 1-3 years out, often applied as seniors but deferred for 1-3 years to do something else; those out more than 3 years. </p>
<p>This breakdown is available on most LS websites and it varies a bit by school. Northwestern has the fewest straight out of UG. </p>
<p>How important what you do is depends upon the strength of the other parts of your application. If you have a 4.33 (at a school with A+s) and a 180 LSAT, you could shoot pool for a year and still get in. I'd go so far as to say that's probably true as long as both your GPA and LSAT are above the 75th percentile at the LS where you are applying--as long as you ONLY take 1-2 years.</p>
<p>If you are down between 25/50% then doing something more meaningful for at least two years could help. These need not be directly career related--Peace Corps, Teach for America and other community service type things can definitely enhance your chances. (It's not going to get someone with a 3.3 and a 160 into Harvard, but it helps.)</p>
<p>It also makes sense if you do something linked to the type of law you are interested in. For example, if you are interested in criminal law, it can help to work as a paralegal in a DA's or US Attorney's office. There's a special DOJ program too that is usually a good credential. </p>
<p>Advantages of waiting: if you work, there really is some truth to the fact that people tend to mature a lot in their first job. It's good to have that seasoning before you go out on the job market. Firms like maturity. They also like references from real world jobs. You may be able to save some dough, so you go into less debt in LS. </p>
<p>Disadvantages: if you have loans from UG, you are going to start having to pay them back. That can be tough on a starting salary. It can also be tough to arrange for the loans to be postponed when you go back to school--especially private loans. You may find that if your family doesn't have much money, you get worse financial aid after working for a year or two than you wouild have received had you gone directly on. </p>
<p>Life can get complicated. People fall in love, for example. Of course, that can happen during college too, but it's especially common in the years right after college. Suddenly, you have to take someone else's wishes into account in choosing which law school to attend. (And if you marry, you may really mess up your chances for fin aid!) </p>
<p>LS has a sort of social life to it, particularly a law school where a good percentage of the class lives in university housing the first year. Living in a dorm can make it a lot easier to get to know your classmates and find out about EC activities and classes. People who have been living in real apartments for a couple of years often find it hard to go back to dorm life. A higher percentage of older students "disconnect" from the social life in LS. They just are past the point in their lives where they are willing to live like a student--but that can make them feel isolated. They may do as well academically, but they make fewer friends and enjoy the experience less. </p>
<p>For people who have the numbers, I'm an advocate of apply and defer. Deferral policies differ, but many top law schools let you do almost anything for one year. Backpacking through Asia is perfectly acceptable at many.</p>
<p>YMMV, of course. These are just my personal opinion.</p>
