Well greetings. I am an international applying to the USA this year, and I have a question regarding transcripts. Since they’re not in English, I need to get notarized translations, which cost A LOT in my country (and I’m not very rich either). I am applying to around 10 colleges - and this is where the issue is. Do I need to send each college a separate original notarized translation (i.e. get 10 translations and pay lots of money)? Or can just sent them copies/scans (this would be a lot better)? Thanks for your help 
You would have to contact each college and find out their policy. However, if I were to hazard a guess I bet each college will want their own notarized translation.
Some will require that you have your transcripts formally evaluated by an organization such as http://www.wes.org/ If you have that done, some will accept the evaluation and will only require an original copy of your transcript, not a translation.
For help with this whole process, contact the closest Advising Center of https://educationusa.state.gov/ The counselors there will have useful information for you.
