How can I have my B1 visa (mistake on name of employer) corrected?

Hello. I am a nanny and I got my B1 visa this morning. I noticed that my employer’s middle name was misspelled and one letter missing in his last name. Would this be a problem in the immigration? Do I need to bring my passport back to US embassy for correction or do I need to apply for new visa? My employer plans to leave for US this June for summer vacation. Thank you.

There is no need for correction. You will be okay. Typographical errors in issued visas are very common.
