How much does a good score on ACT/SAT increase my chances whereas I can waive them?

Thank you so much @Lindagaf I think it’ll hurt my app if my score is low!
You know I want to do my best for applying to USA, I think that I’m talented and diligent enough to not waste my time and energy in a country which there are very fewer opportunities to grow. and also my brother is in the process of receiving his green card so he can’t travel Iran, as far as Trump’s politics my mom also can’t travel US which she’s suffering from because she’s missing my bro and she hasn’t met him for 8 years!
Bowdoin is a liberal arts college, would it affect my career future? and as you said it’s test optional, But it has published its average test scores as far as it’s so competitive it seems not taking the tests will hurt my chances.
I would be so happy if the universities don’t care about the tests and consider my situation but many make me desperate by telling that the ACT/SAT show your competitiveness and academic preparation.
