Dont have I-129S for L1 Visa

[LillianRoot]

Hi,
I recently applied for Blanket L-1 Visa and got my visa approved. I received my passport back from Consulate with visa stamped on it. However, they did not give back any stamped/approved Form I-129S to me. Now, the visa states that I must present Form I-129S at POE.

I am trying to reach US Consulate via their support emails but no response so far.

Questions -
1. Is it mandatory to carry I-129S for my first https://xender.vip/ visit to US? Will I not be allowed to enter US if I don't have it?
2. Is there any other way to expedite my process of getting I-129S from US Consulate other than contacting via support?
3. How much time do they take on an average t https://nox.tips/o respond to such queries?

Thanks.

I-129S you will receive at the interview time itself. Ideally they will keep one copy and give two to you. Ideally they won’t forget. But if it happened talk to them. This is required to travel on L 1 to US
