No power of attorney, no standing in for you, just a guide for a very complicated process. From what we've seen, it's generally intended for people who would otherwise DIY the process, but want a little more peace of mind that they're doing it right. It's not really meant for those with complex situations that need a lawyer.
That;s the danger. If they are giving advice that results in you submitting different answers that you otherwise would have, they are boarding on giving legal advice. It's all well and good when things work out, but when that advice goes wrong it can be very very bad for the client. That's why lawyers are licensed. These people are also handling lots of personal information that I hope would be covered by attorney-client privilege, but only if they are lawyers.
Certainly this is the case with tax lawyers and reading through this thread there are quite a few instances with immigration lawyers.
TurboTax is useful because it provides an easy interface for doing your taxes -- electronic filing is just a bonus. Say IRS only accepted paper forms. It just means that you would have to print your return documents from TurboTax and mail them (an option that is still available in TurboTax). Mailing in IRS forms is not the hard part, it's filling them out. TurboTax was able to replace tax agents for most people because it guides you through the process and does all calculations for you. eFiling is just icing on the cake.
Question: Who actually submits the documents? The 'How it works' is not clear.
"The application, upon completion, is sent to a SimpleCitizen-approved immigration lawyer for review to ensure users have the best application possible." ...But then what?
One of the reasons you hire a lawyer is so that lawyer can stand in for you. Part of that is that they can submit documents and requests on your behalf. Does SimpleCitizen seek power of attorney from customers? That would open a nest of licensing issues. Note the careful language. Are these "review" lawyers giving advice or not?
