Hello ehab222,
I was traveling between July 2015 - January 2017 and have traveled to 4 countries. However, my main hub has always been Indonesia. Since I wanted to explore the country a bit more, I have lived there for quite long and have visited the nearby countries for the visa run, whenever I was on the verge of exceeding 6 months. Besides, I have mentioned that I have been traveling for 1.5 years on my application as well, but haven't mentioned any detailed timeline for that duration. I thought, if they want to check the details, they could always refer to the copy of my passport pages.
Is this going to be an issue?
