Payment Gateway Recommendation? Non-US citizen, with US store

[Melissa_Ah-Sing]

Hi, I've just been disapproved by Shopify payments, although my store has been running couple of months and making sales. Any recommendations for payment gateway alternatives? I am a non-US citizen, who lives in Asia, but has a US LLC and shopify store that deals with US suppliers and US customers only. Other gateways such as authorize.net, only accept US citizens, so far I'm stuck ! Thanks
