I & my family are currently in the US based on my L1A. The visa stamping expired in Dec 2012, but we have I-94 till Oct 2015. Our max-out date of 7 years under L1A is in March 2015. My company might file I-140 now under EB1 and in my case since I will be in the US it will be adjustment of status. If my family goes on a vacation to India, I understand they can apply for a visa while in India against my I-140. My questions are (1) when my status gets adjusted, what's the document based on which I continue to stay? Will I get restamped L1A on my passport or just continue based on my I-94? (2) When my family is approved visa, what stamping would they get on their passport?
