Which bank should I open a USD account with as an American living abroad?

I plan to create a USD bank account for the purpose of generating revenue online and online shopping. My aim is provide web development services online and other digital products, hence, I believe a USD account would minimize the complications of financial transactions on an international scale.

However, as an American citizen, I live abroad, specifically Trinidad and Tobago. I lack necessary US documentation as I moved before becoming a teenager, so I don't have basic identification such as a national ID for the US. Thus, I would like to know which bank(s) would be best to open up a USD account as an American living abroad as I do plan to making a visitation to do so. However, I would be a bonus if I can do so online.

I generally lack much financial knowledge when it comes to international transactions, so if there is a better way to approach this issue, please educate me!
