I think the California (CA) legislature has created an impossible situation with there laws related to immigration forms, and the CA Secretary of State (SOS) has made it worse.
One problem area is the law that prevents CA notaries from completing immigration forms (unless all they're doing is a notarization). unless the notary is also an "immigration consultant" or lawyer. This law applies specifically to notaries; non-notaries can do immigration up to the limits that the federal government allows. "Immigration consultants" are mainly allowed to translate the questions on the form to the client, listen to the client's answer, translate the client's answer to English, and write the answer on the form. I think it's just about impossible to do the translation without giving some legal advice in the process, but giving legal advice isn't allowed.
The SOS made it worse by deciding that Form I-9, which all new employees (including citizens, green card holders, and other immigrants with permission to work in the US) have to fill out, are immigration forms. Remote employees are often referred to a notary to get the form filled out; there is no notarization, the notary acts as the company's representative in filling out the EMPLOYEER'S part of the form. So the SOS is saying to fill out I-9s, the notary must also be an "immigration consultant", but the "immigration consultant" is only allowed to essentially take dictation from the client. But as the employer's representative, the notary is expected to make his/her own statement that he/she examined the ID and it appeared proper. So, it seems to me CA notaries can't do I-9s at all, unless they're also a lawyer.
