Travel to US before filing for H-1B amendment petition

Hi,

My H1B is filed for location A, but I had to travel to location B. So my company applied for new LCA. With the new LCA I travelled to US during last year. Now I came to India due to personal emergency and I am planning to travel back to US early next week.

But now my company tentatively saying that I have to file H1B Amendment Petition before I travel due to April 9 H-1B Amendment rule. Even my company is not sure. I don’t have time to file my Amendment too since my flight is booked for early next week.

If I travel, will I face any issues at Port of Entry?
