I am a Canadian working in US with TN Visa. My wife is Korean working in US with O-1 Visa. And my son is US Citizen (born in US) since we met and got married in US. My wife wants to apply for the green card (O-1 to greencard) and am I (family member) also eligible to apply through (piggy backing on) her process? To make conversation easy, let's say she's qualified to apply for the greencard and my company is not willing to sponsor me for my 'TN to greencard' process.
