Since your transcript already explains your 17 years (10 years Saudi + 7 years outside), in Comments you can write something simple and natural, like: Option 1 (short & simple): I have 17 years of total experience, including 10 years in Saudi Arabia and 7 years outside Saudi Arabia. I know all laboratory works including soil, asphalt, concrete, and aggregate testing. Option 2 (slightly professional): I am fully experienced in civil material testing with 17 years of work, out of which 10 years were in Saudi Arabia. My skills cover complete laboratory work for soil, asphalt, concrete, and aggregates, along with quality control and reporting. Option 3 (very short, in case space is limited): 17 years’ experience (10 years Saudi Arabia + 7 years outside). Skilled in soil, asphalt, concrete, and aggregate testing.
