Seeking Advice on Protecting Our Young Ones in a Non-Muslim Land

Assalamu alaikum, dear brothers and sisters. I'm a Sudanese man, born and raised in the UAE. About two years ago, my family and I made the move to the USA. Lately, my heart has been heavy with worry for my younger siblings, who are 15, 13, and 10 years old. My concern grows each day, fearing the influence of this non-Islamic environment and the haram that surrounds them. I've spoken to my parents about the possibility of returning, but they are anxious about finding work back home and the prospect of having to relocate to Sudan if they cannot. This matter occupies my thoughts constantly. I would be so grateful for any wise counsel you could share.
