A few questions regarding a Canadian citizen in the US.
- Is a Social Security number required in order to work or is a TIN sufficient?
- If the person is in school but working part-time as an intern at a company, he or she still must have FICA and Medicare taxes withheld regardless of number of hours worked in a week, right?
Note: I have confirmed that the person has a TN visa, not a TD.
Thanks, Gary
