Last Name not written in passport and Visa is in processing state

Hi All,

Can someone please help me with Last Name issue.

I have my passport without Lastname and only “ABC” as firstname. My visa is in processing state for 2015 after lottery and i have time in stamping to get new passport with full name as got married between that time. But if i get my passport updated, would the already sent visa petition got rejected or will there be any issue.

Please please let me know what should i do.

Your last name DEF won’t create a issue’
