Basis for original birth certificate to sponsor family for a visit

[baghloli]

Good evening,
While preparing documents to sponsor my family members to visit me on a tourist/visitors visa, I noticed that original birth certificate is required.
"If you are a non-U.S. citizen:
Your Original birth certificate. If you are sponsoring your in-laws, your spouse's original birth certificate is required instead. "
I am a green card holder, and during the green card filing process, I provided original birth certificate, Hence, the my birth record was verified by immigration during the green card process. I am wondering if this is really needed during my family sponsorship. Can I use the copies of birth certificate instead?


Thanks

Yes, it is really needed.

Many thanks for this information. I couldn't locate my birth certificate, looked everywhere in the house , bank safe etc. I thought I lost it and it is really a pain getting a new one. That's why I wanted to use the copy of the birth certificate, which I have plenty in my possession.
Finally, I found out that it was with my parents back home. I send it when I filed for their visa sponsorship a few years ago. In any case, its important to have this critical document in one possession at any time.

Regards,
