What are my chances at grad school in Intl Affairs?

<p>I'd like to apply to NYU-Wagner, Columbia-SIPA, GW-Elliott and American-SIS for a Masters in Intl Affairs, public policy.
GRE: 550V/680Q/4.5A
GPA: 3.8, Honors, Magna Cum Laude
Good recommendations
Local work experience in Conflict Res. and an internship at the Wash Dege of the Euro Comm for a total of 7 months.
A good amount of abroad experience for travel and school.
My GRE scores are weak compared to what's listed here and my work experience is not for a significant amount of time. What do you think my chances are?
Thank you for your help!
Anyone willing to read my essays?</p>
