I can't believe I made so many mistakes in my initial application to CIO.Although I was recommended to a visa office for processing.Can I correct that error ,which unfortunately was overlooked by the CIO?Such mistakes included wrong time duration at my former place of work and many gaps which i did not account for.Is it okay to fill in the gap.For example I didn't fill any employment or activity between 2004 and 2005,whereas I was was working.Is it okay to correct this oversight?
