No SSN and credit score for LLC and owner available, just business model and good standing LLC.
Residence is not a factor for venture funding -- what's important is building a network so you can get in front of the right people in the US venture community.
Loans for small businesses are really restricted to established businesses with clear cash flow and preferably some obvious assets (like real estate). Most startups can't get a small business loan. Does not matter whether you're a US resident or not.
Also why do you have an LLC? It is the right structure for some companies, but not others.
Happy to discuss further.
