I am considering pursuing an advanced degree in either Tax or International Tax.

My class standing within the top 35 or 30%, and I have maintained a GPA of 3.4. I have earned a GPA of 3.5 in five tax-related courses, encompassing Income Tax, International Tax, Business Planning, and Corporate Tax.

Considering the information provided, which institutions might offer favorable prospects for my admission?

I'd say schools like NYU, Georgetown and Pritzker would be great options to look into given your background.
