We are in our 6th year stay.My wife just got a job.If she files for H1B for how how long will she get it.My company is filing extension based on our green card (labor has been applied for more than 1 year ).Will she be allowed to work only till end of 6th year or during our extended stay too.If she is allowed to work only till end of 6th year we'll have to get her transferred to H4 again?
