This is strange that they gave you GA waiver of $20k only for 1st year because usually the schools either distribute the amount over a period of 2 years. Maryland has quite a strong reputation in Sciences and is one of the top universities in east coast. Their MBA program is also reputed not as reputed as the other programs though as Maryland is primarily known for its research work,according to my research. Getting a job is definitely more difficult for an international student and you'll have to really polish your skills and build a strong network during the 2 years of your program.
I think the current students at Smith will be able to give the best insights into the pros and cons of the school.
