Is living abroad an advantage for college admission?

Thanks! Also are freshman grades very important? Ive never gotten below a B on my transcript however, my grades weren’t so great last year. But every term my GPA has improved . i went from a 3.6 (US GPA) up to a 4.0. and this year my grades are really good with a hard course load. My only concern is that the B’s i got are considered A’s in the US. Are these colleges aware of this? I’m just worried that they won’t acknowledge that i am basically doing all honors classes.I’m doing the Cambridge IGCSE system and according to Cambridge:
A- 4.0
A-4.0
B-3.7
C-3.0
D-2.7
I do 10 subjects a year with A
and A’s in most of them. But in my freshman year i got quite a lot of B’s. Will that hurt me??
