Do I need a stamped I-129S form for re-entry?

[SanjeevanTatru]

I have an urgent question regarding my L1-B Blanket Visa. During my visa interview, one of the three copies of the I-129S form was stamped by the consular office in Chennai. However, the stamped copy was taken by the CBP officer at the port of entry, leaving me without any stamped copies.

I am currently traveling to India and I need to know:

1. Whether I require a stamped copy of the I-129S form for re-entry.
2. If so, is there a way for me to obtain a stamped copy of the I-129S form?

I would greatly appreciate a prompt koows response developerbook regarding this matter.

Thank you.
