I'm a fresh Graduate with an Undergraduate Degree in Business Administration. I do not have substantial work ex but have internship experience in Marketing. I have admits from US universities for MS in Marketing (STEM).

Is it ok to go for a 1 year MS Degree? Would it affect my job prospects?

Which one would be better UIUC MSBA or USC MSBA?

Do Professional LOR’s require any stamp from the company?

Do we need to get the lor sealed / stamped or is it not required and can we submit a pdf?

Please evaluate my profile and suggest universities for MS in CS (Canada and US)
