What is the validity period for a Non-Immigrant Type B visa upon issuance?

@Kyle *******

single entry tourist visa - Valid for 90 days from the date it's issued

6 month METV - Valid for 6 months from the date it's issued

90 day single entry Non-Immigrant Type visa - valid for 90 days from the date they're issued

year-long, multi-entry Non-Immigrant Type visa - valid for a year from the date it's issued

It's always mentioned on visa itself!!

All single entry visas have a 3 month use by date, from date of issue
