@Kaalubaby -- Technically there is no relation between H1-B and green card process. They are separate and has no impact on each others. But then in the practical world they go hand by hand. To answer your question, You don't have to be in H1-B to file green card. Most of the people forget to realize that green card through employment is for future job and future positions. But that's usually not the case in the real world. Any company can start your green card process right now. But I know its hard to find company doing that. Also, you can work for some company on H1-B, and another company can file your green card process. Hope this helps answer you questions. Also, consultancies can file green card right now, from the day you have H1-B.But this is very unlikely. Best case Scenario after 6-12 months they might start the process.
