Double Major (cs + eco) At TESU, for a french guy ? Possible ?

[Phil9444]

Hello everyone, I'm new to the forum and this is my very first post. 

Thank you for accepting me.

My name is Phil, I'm 26 years old, I only have a BAC (equivalent to finishing high school for you Americans), and I'm French.
Just a few days ago, I discovered the (very interesting) world of “Degree Hacking” through a YouTube video that was suggested to me (about WGU). 

I then asked Gemini a lot of questions, and he explained everything (or almost everything) to me... At least, I hope so.
However, I still have a few questions.

I would like to obtain a bachelor's degree in computer science at TESU. And I understand that it is possible to have a double “area of studies” (a double major) on the diploma.
I would like to combine computer science with economics, do you know if its possible ? Or computer science + maths ?

Of course, I have skills in both areas (especially computer science), and I have been coding for several years.
Do you know if these two combinations are available? 

I would also like to know if it is possible to have minors in addition to majors.

Next, I would like to know if you know any French people on the forum, so that I can contact them, or if you know any other French people who have been able to follow this path (because I feel like I'm the only one interested in TESU's offerings in France).

My ultimate goal (via the TESU bachelor's degree) is to be able to apply for the Georgia Tech online master's degree (in computer science): https://omscs.gatech.edu/about-omscs.

If you have any advice or suggestions for me, please don't hesitate to let me know. I would really appreciate it.

Best regards.
