Which US forex broker do C2 autotraders prefer?

I am about to start trading a forex strategy with C2 as a leader, but I am based in the US which limits my options. Can any one give me their preference for a US forex broker with respect to autotrading a strategy? I was told there is only IG and Trade Pro for US clients. Also, it is possible for overseas investors to autotrade a strategy that uses a US-based broker?

If you are in the US, your choices for forex are IG and StoneX (TradePro is the introducer.)

Regardless of the fact that you are in US, your subscribers who are outside the US can trade at any Collective2 compatible broker. They do not need to use the same broker as you, so the fact that you are restricted due to being in the US does not affect subscribers outside the US.
