u/Cider95

I know there is no such thing as a renewal but I am applying for a new TN with the same employer and job title. What are some things I should know before hand?

Do I need to update my employer with my new i94? (If successful)

Do I need a new SSN? Is my SSN tied to my i94?

Do I still need to wait until 10 days before my current one expires?

Any advice appreciated ◡̈
