Hi Peter, I've heard people mentioning they transitioned from TN visa to green card sponsorship, my understanding is that this isn't allowed, have you heard of this?

[proberts]

It's definitely allowed but there are certain minor requirements and restrictions specific to those in TN and other non-dual-intent statuses.

As an Australian E-3 holder, what kind of requirements/restrictions?

[proberts]

We should talk. Although an E-3 is like an H-1B, there also are significant differences.
