visw.rupa75

Hi,I am in the process of renewing B1/B2 visa which is expiring on Dec 21, 2019. I am given to understand that there is a possibility of interview waiver. I have a query:Under Travel Information, there is a question " PURPOSE OF TRIP TO US". I have selected "Temporary Business Pleasure Visitor (B)". I am then asked to Specify.The options are :1. Business and Tourism (Temporary Visitor) - B1/B22. Business Conference - B13. Tourism / Medical Treatment B2My existing Visa Type / Class is B1/B2. Hence, I have selected B1/B2 under the "SPECIFY OPTION" in DS-160.I am just a little confused. Please let me know if this is fine. I understand that the Type/Class of Visa should be the same while renewing to avail of the Interview Waiver.Many thanks!RV
