All the answers here are based on old form. For example,Jonny has filled his application in June 2017 meaning using older version of 485. Lets say if Jonny had worked in 2010, using old form he can easily say ‘NO’ as the question only asked for the last 5 years. However, after August 2017 there is an additional question ‘have you ever..’? . so all the applicants who commented here did not go thru this question as all were before August 2017. Still there is no right answer for the question raised by Nepal 1827.
