How long is validity to apply for GC when priority dates are passed?

[Ambhpatil]

In case if I miss my Priority date then how long will be validity to apply for Adjustment of Status? In one Forum I saw that within 1 year you have to claim that adjustment of Status.
In case if I miss to claim within 1 year what all my options?
Two Scenario may happen with me
1) If I come back to US after 1 year of priority date from the same company who has filled my GC? Can I still apply for Adjustment of Status?
2) If I leave my company and come back to US through another Company?

Kindly let me know answers on both the cases

Hi Member,
Please see my response below.
1) If I come back to US after 1 year of priority date from the same company who has filled my GC? Can I still apply for Adjustment of Status?
Answer: As per my knowledge, you will have only one year to file the petition after your priority dates come current. Afterwards, if you miss this, the government will perceive you have quit, and the next person in the line will get your visa number to the next.
2) If I leave my company and come back to US through another Company?
Answer: Most probably, you will need to run another petition from the scratch.
For more clarification, you can contact Immigration Attorney.
Thanks
