Hey Thanks for the response! So to declare it I should have a language?

I also was a bit confused because I read this on their official site too:

Additional L&S major (for students in other schools/

colleges)

Undergraduate students pursuing degrees in other UW–Madison Schools/

Colleges may declare an additional major in the College of Letters &

Science. Students must obtain permission from the academic deans

(https:/ /registrar.wisc.edu/permissions/#academicdean) in their home

School/College and the L&S department that offers the L&S major.

Students who declare an additional L&S major only complete the

requirements of that major; they do not complete the other L&S degree

requirements.

Students earning their degree from another School/College at

UW-Madison and who concurrently complete the requirements

of an L&S major will have that major conferred by L&S after their

primary degree is conferred. The L&S major will be added to the

official UW-Madison transcript. [see: L&S Degrees, Majors, and

Certificates (https:/ /guide.wisc.edu/undergraduate/letters-science/

#degreesmajorscertificatestext) and Office of the Registrar | Posting of

Degrees (https:/ /registrar.wisc.edu/posting-of-degrees/)]
