To person with limited knowledge and to the original post - In advance (correct me if I am wrong)...

Raman, please do not fall for this as everyone suggested (and do not tell "afu chahi america jancha and bascha, aru le try garyo ki, daha garchan). I wish one day you will come here.

Also, the way you have asked question, it clearly tells me that you have very limited knowledge on this and the process. EB3 is not a visa category. Initially I thought maybe you were inquiring about Investment VISA and green card process. EB3 is a category of " Green Card process through employment".

Neerman sir/bro/sis, I have noticed that you always reply on immigration topics (I guess to help our fellow Nepalese), But many times I have realized that your response are in-accurate and in-complete. Again, green card process through employment is for future employment. You can be in any part of the world and apply as long as you meet those criteria. And this is why we have two methods during last step of 485 - Change of Status and Consular processing (for people outside of US).

I am not sure how it is these days, But back in 09, 10, and 11, H1B filing used to be full in just few days because half of applicants used to be from India. They have made sticker rules and therefore we do not see those trends anymore. You can still come from any parts of the world through GC process under ant category.

So Raman, Again do not fall for this. Again what you can do is, ask them to process your GC using their money and tell them you will pay them when you are here in US once you have GC.

Hope this helps and please do not take it personally.
