Hello, I'm graduating in administration and would like to migrate to data science area, I must attend a college of computer science?

Changing from administration to data science could be an exciting career move, and I agree with Mi Gao that school and certification will be much more helpful than self-study or "bootcamps", especially on a resume. One thing to keep in mind is that a data science career will be much more numbers and math-focused- be prepared to do more calculations and critical thinking in your job! If that sounds fun to you then definitely pursue data science programs at the undergraduate level. Most if not all data science jobs require a mathematics-based undergraduate degree at a minimum.

Based on what I knew, to take the learning in college was much useful for you to take the knowledge you need purposeful and directly; and they can give you the certificate which I thought is the most powerful evidence in the real outside world. Although the ability is first standard in my opinion, this will give you the support when you look for the job or when HR do the filter to the resumes.

Although you might also can get what you need as a programmer by doing Self-study or somewhere such as code bootcamp, I did not think this also work for data science area.

While a degree in Computer Science is not a "must", it will certainly provide a strong foundation. You could also pursue Computer Technology etc. There are a lot of free on-line course available for data science. I suggest you look into them and get an idea. These websites also offer certifications at a very nominal price. Hope this helps.
