Am I eligible for porting my green card from EB2 to EB1?

[legalresident]

I am currently on H1B VISA (4th year) and my Green Card stage is I-140 Approved in EB2 category. I am in USA from last 3.5 years and before that I worked for the same employer from India on managerial position. If my employer is willing to port my green card from EB2 to EB1, it is possible in EB-1C? My major confusion is on the below clause:

"You must have been employed outside the United States in the 3 years preceding the petition for at least 1 year by a firm or corporation and you must be seeking to enter the United States to continue service to that firm or organization". 

I found the below in favor of me in another website:

"If the alien is in the United States working for the petitioning employer, in the three years preceding transfer to the U.S. as a nonimmigrant, the alien was employed by the entity abroad for at least one year in a managerial or executive capacity"

Since I am in USA for more than 3 years, am I still eligible for EB1 (or) Did I lost my chance? Please help.

You do not seem to qualify as you have not worked for one year in the preceding three for your employer back home.

Hi - did you get your porting approved ? Is your I140 done ?

HI @legalresident, 

Even I too have the same query and in the same situation, planning to port my EB 2 to EB 1. Since you have posted your query 3 years back, do you have any updates.. did you ported your EB2 to EB1. Please let me know.
