That's the same problem I am facing. Some ICOs geo-block if you are from USA. Using VPN has helped gain access to the site but some have KYC which is impossible to clear if your ID is a US ID. Ones that don't have KYC can be accessed using VPN. Here
is one of the websites I use to track ICOs. The rightmost column gives quick information about geo-restrictions, KYC requirement etc for each coin. I have found this to be very helpful while shortlisting coins. Hope this helps! :) If it did, here are a few ICO's I invested in and have a referral code. If you like the ICO, maybe you can use my referral. :)
