Hi Everyone, 

I just joined this forum and seems very helpful. I am currently working on applications for an M.Arch I program in the US. So far this is the list I have made of the universities I am interested in and have caught my attention either because of their programs or the location they are in:

Harvard GSD
M.I.T
Yale
Cornell
Princeton
U.Penn
Columbia
UT Austin
U Oregon
U Washington
UCLA
I.I.T
UBC (Canada)
UC Berkeley
ASU

My background:  

25/M/Quito, Ecuador
B.Arch -  University of New Mexico GPA 3.85

-Got a Honour Mention at an international design competition in school
-Worked for a year in Albuqerque, New Mexico as an intern architect, energy/performance designer, daylight analysis and LEED. 

-Have worked for 2 years now in a top architecture design firm in Quito, Ecuador as a project manager, lead designer. We won one open competition for a school with my design, and several mentions in other competitions. 

This is an example of a project I was a leader of and designed:

-I have been involved in project construction, management  as well. 

-I have one personal project built, a very conceptual house in a coffee plantation. 

I know applying to 15 different programs is excesive. Is there a number of programs people usually apply to? Is applying to 10 a good number or perhaps too much?

Do you think my previous professors would have a problem doing letters of recommendation for 10 different programs? Are the letters of recommendation different for each school or they just make one and send it over to each school?

Thank you so much for your help!
