Are you asking if you can afford someone from Kenya for $1100/month? Those type of transactions are...just no.
First, are you a USC?
If no, then are you an LPR?
If no, then that's that. Nothing really to do other than to keep chatting and go visit her.
If no to USC and yes to LPR, then the only option, if the relationship is genuine, is to meet, spend lots of time together, and file for F2A spouse of LPR visa.
If USC, then meet, spend lots of time together, and file for either K1 fiance or CR1 spouse visa. Spouse visa is superior.
Before any of this, save up as much as you can. The above processes are expensive, both in fees and in expenses to visit and establish a relationship.
