Foreign Language requirements for US undergrad admissions

I’m a US citizen studying (to be enrolled in 11th grade) in India in a Cambridge International AS/A level program. It offers 2 tracks (Science & Commerce) and neither of them have foreign language in the curriculum. Unfortunately I did not take any foreign language courses during my 9th & 10th grades either.

Many of the US universities seem to require atleast 2 years of foreign language. Is this requirement a must-have or can this be substituted with a SAT Subject test in German/French for example?

I believe this requirement does not apply to those studying outside the US, for international students etc.

Still, to make sure, you may have to email some universities.
