Visa extension

[immihelp]

I have a friend who is interested in extending his visa... He has filled
out the necessary paperwork but is unsure of who he needs to make the
payment to for the visa. If you could let me know that would be
appreciated!

Thanks

Which visa?

I believe it's a temporary worker visa
