Question for the OP: do you also have the usual college-prep high school curriculum (4 years English, math to precalculus or calculus if available to you, 3 or preferably 4 years of history and social studies, science including all three of biology, chemistry, and physics, visual and performing art)?
If so, meaning that the second foreign language did not displace any of the usual expected college-prep courses, then it is perfectly fine to take it as academic electives beyond the usual expected curriculum. But if not, meaning that you are deficient in some of the college-prep high school curriculum, it may be disadvantageous when applying to more selective colleges, and you may find problems in your preparation to attend any college.
