How long is it possible to keep extending the H1B visa and is it necessary to file for a Green Card?
Mrs D. Roy Answer The maximum period allowed on H-1B visa is six years. H-4 time period is also included in this six years. However if you have a labor certification pending for more than 365 days you can keep the H-1B visa extending in one year increments. Therefore if you want to stay here for more than six years continuously you have the file for your labor cert. leading to permanent resident status.
