<p>Are you sure it is not a work visa instead?</p>
<p>My son-in-law, a Canadian graduated from a US law school and is an attorney at a top NYC law firm for 6 years. He is still on a TN visa (NAFTA visa for N. American professionals), His firm has hired many British citizens but he isn’t sure whether they have a work visa or green cards.</p>
<p>My daughter has just submitted application for a green card for him and they have been married for more than 2 years. He wasn’t in a hurry to change his status.</p>
