The team could certainly do much better on this front, but also keep in mind that immigration processing and interview times tend to be much more drawn out in major metropolitan areas. It's a function of population and the sheer amount of people requesting status.
(And, frankly, there are much larger entities than RB vying for the services of top notch legal counsel).
Now this is the transfer news we've been waiting for! Epps was in a tough spot. He doesn't seem like he can beat out the other first team wingers, but he's a stud at the USL level. This opens up a first team roster spot and allows RBII to play some guys with a higher ceiling, so it seems like a good move for everyone involved.
You could probably make the argument that Reyna was a top tier DP as well. His European resume was pretty much as successful as Cahill's, aside from not being a club legend at a smaller side. Obviously, he was past it when he got here, but the guy captained Wolfsburg and was a stud at Rangers, as well as captaining the national team.
