Please remember that in the United States only a licensed attorney (a lawyer) is authorized and qualified to give you legal advice, help with your immigration applications, forms, etc.
A Notary Public is not an attorney. To become a notary, a person has to pass a simple test, but doesn't have to be a lawyer, doesn't even need a college degree! (It is very different in Russia, Belarus, Kazakhstan, Ukraine, Europe or Latin America, which is why it is confusing to immigrants from those countries).
For convenience of their clients, many lawyers also hold a license of a Notary Public in their state. However, these lawyers are licensed attorneys.
Please do not be fooled by people who offer to help with your immigration paperwork for "reduced fee". Or offer your "free legal advice". As they say, free is only the cheese in the mousetrap.

Briefly in Russian:
Нередко нам приходится помогать людям, которым до нас "помог" нотариус или "иммиграционный консультант", и в результате испортил их шансы на получени грин карты и гражданства.
В США нотариусы не имеют право оказывать юридические услуги, в том числе иммиграционные услуги, такие как подача заявления на полит убежище и разрешение на работу. Для оказания таких услуг нужна лицензия адвоката (а не нотариуса).
В США нет иммиграционных консультантов (как в Канаде, например), которые в тоже время не являются юристами. В США только юрист может быть адвокатом и оказывать юридические услуги, в том числе иммиграционные услуги.
Если вам так "помогли", вы можете пожаловаться властям штата или федеральтным органам власти. Это не будет использовано против вас, но сможет остановить такого "помощника".
