I am going to Ghana to marry my fiance we haven't met face to face before will it be hard for him to get any kind of Visa to come back to the USA.

If you are a US citizen and get married to a Guyana National in his country, he can process his green card application at the consulate there and once it’s available, he can enter the USA. There are other options available. Discuss with counsel to explore the best course of action. Counsel anywhere in the USA can help you.
