I applied to GW as a transfer but did not attend (I went to a T14 instead).
GW sends a lot of students to NY. Like I said before, it will be easier to get a job in NY compared to DC because DC is a much tougher job market. GW is regional, but it's region extends along the east coast and it has a pretty good rep. It's rep doesn't extend as well in places like Chicago or LA.
One major downside to GW is the class size. It's large class size means placement is not going to be a good as a comparably ranked smaller east coast school like BC, for example.
Also, I've heard that GW transfers don't do as well in OCI as they would have if they transferred to a T14. But that is true of any school in the 20-25 range.
What other schools are you waiting on?
Personally, I'd go to a school like Vandy or BC over GW. Then GW over WUSTL if you really want NY placement. I'd go to any T14 over any of these schools, however.
