Forming an LLC in the US offers non-resident entrepreneurs access to the world's largest market, increased credibility, personal asset protection, and ease in opening bank accounts and raising capital. An LLC combines partnership flexibility with corporate limited liability, avoiding double taxation. The process involves choosing a state, naming the LLC, appointing a registered agent, filing Articles of Organization, creating an Operating Agreement, obtaining an EIN, and opening a US bank account. Challenges include complying with US tax laws, identity verification for bank accounts, obtaining an EIN without an SSN, understanding immigration rules, and navigating US employment laws. Professional guidance is recommended.
