Hi againHi there Dakota,
There are a lot of people who apply for visas without the need for a lawyer or agent. Although the visa criteria are very confusing and applying is time consuming, many people get their visas successfully on their own.
Getting an agent or lawyer could be an option if you don't have time to manage the paper work yoursellf, or if you have a 'difficult' case i.e. you have a health or character issue that could cause your application to be rejected.
Tell us about what visa you're interested in and we may be able to give you some more specific information or advice
