Insufficient post-journeyman hours – Only hours after getting your journeyman license count.
Unsigned/notarized affidavits – Every employer form must be notarized.
Criminal history not disclosed – Even minor offenses must be reported; failure = automatic denial.
Using out-of-state experience without reciprocity approval – Texas only accepts experience from select states (e.g., Louisiana, Oklahoma).

A: On average, 3–6 months—depending on how quickly you gather documents, schedule the exam, and pass. Delays usually come from incomplete affidavits.
