Second Ac21 similar/same job question??

[desp_gc]

I am considering moving to a different company..

What happens if I do not file an AC21?

Can I file an AC21 if the the job is similar but not the same?
for ex..I filed my gc using a set of technical skills like oracle,c,C++ programming,engineering background..
now I am using a different set of technical skills in new job..engineering back ground, excel..

Will this cause any issues?

Thanks to everyone for responding,hoping that this bulletin may get me a green card but I rather look forward
to the weekend

------------- if you dont file AC21 or dont update USCIS and your I-485 has job offer letter of employer A then your I-485 will be approved for A to work with A after GC approval. if you are eligible to use AC21 and want to work with employer B better file for AC21
Can I file an AC21 if the the job is similar but not the same?
-------------- check the LC form ETA750A it has your skills, better get the permanent job offer letter from new employer with same job duties
for ex..I filed my gc using a set of technical skills like oracle,c,C++ programming,engineering background..
now I am using a different set of technical skills in new job..engineering back ground, excel..

Will this cause any issues?

Read the May 12, 2005 MEMO by William R Yates. question 3 and 5
Question 3. What is “same or similar” occupational classification for purposes of I-140 portability?

Answer: When making a determination if the new employment is the “same or similar” occupational classification in comparison to the employment in the initial I-140, adjudicators should consider the following factors:
A. Description of the job duties contained in the ETA 750A or the initial I-140 and the job duties of the new employment to determine if they are the “same or similar” occupational classification.
B. The DOT code and/or SOC code assigned to the initial I-140 employment for petitions that have a certified ETA 750A or consider what DOT and/or SOC code is appropriate for the position for an initial I-140 that did not require a certified ETA 750A. Then consider the DOT code and/or SOC code, whichever is appropriate for the new position to make a determination of “same or similar” occupational classification.
C. A substantial discrepancy between the previous and the new wage.
