The Visa Machine have been crossing the t's and dotting the i's on rally team visa applications for over a decade now. The Visa Machine was born out of The Adventurists, they are now a separate company but still work in partnership with us. Here's a really useful help page they made especially for you lot. They have also created this rather handy visa information tool.
If you like what you see and want them to help you with your paperwork head here... or drop them an email (firstname.lastname@example.org).
The Adventurists don't do Visas, although we recommend The Visa Machine.
