@Jeff ********
It is what it is :/
BUT
Just so you're clear, it doesn't "mess things up for others" in the least. IF you qualify for a visa/extension go file at your office and it'll go thru just fine.
If you don't well then you start looking for 'alternative options" ;)
Agents have been around as long as visas/extensions have and they're certainly not going any where any time soon.
The main concern is you find one of the BIG players so you're paying the least and your passport is going thru the least number of people to get what you want done.
It's the people who use an agent/agency that isn't a big player, that brokers their stuff thru another agency that run into problems.
