CMU CIT OR UCLA?

Hi everyone! My name is Albert and I was admitted to CMU engineering college and UCLA college of letters of science. I am interested in environmental science/engineering. I’m an international student and I would like to potentially stay in the U.S. and seek employment after graduation. I’m torn between the two great schools. Personally, I like UCLA’s campus and students but I feel that CMU’s program is stronger and more prestigious.
Do you guys have any advice?
