Please do your own research, rather than relying on the agents. Especially if you're a normal semi-intelligent person, you shouldn't run into any issues. If you do want to take help, use a qualified attorney, not an agent.
My brother went to 2 agents in India, to see if he can qualify for EE FSW. Both said he didn't have enough points to qualify. I had to walk him through the CRS to show that he can, in fact, get 450+ points, if he can score CLB 9 in IELTS. Now you'd think that those agents would oversell, considering they would want to make money. This shows most of these agents don't have up to date information, or they just don't care enough to dig deeper.
