Can we use Business Visa to enter US when you have a valid L1B Visa

[potamo]

Hi All,
I have got a valid Business Visa and a L1B visa (recently granted and valid until July,2022). Now there is a Due Diligence requirement where my Company is asking me to travel US on Business Visa. Could you please clarify whether there is any risk in travelling in Business Visa when you have valid and unused L1B visa.
Is there any probability that at POE, the L1B visa is cancelled when you try to enter with B1 Visa. Please let me know ASAP

You are all good to travel to USA on B1. Ensure you inform the officer at POE that you intending to use your Business visa (& not L1 visa).

Quite possible he might ask you question related to your L1 visa, if you've changed your employer or project etc, then he can cancel that. If you are still with the same (L1 sponsored) company & just travelling for a short term (not really switching payroll to USA) you'll be allowed entry easily.
