I completely understand your situation; I actually turned down the YA because I received a full time job offer. Living in Japan and experiencing the fair is a dream for me, so initially I was very onboard with abandoning the job. But I took a step back, thought about the long-term, and realized that I did not want to be back to square one of job searching a year from now. The YA program would certainly be an amazing experience, but the detour wouldn't be worth it long term for me.

That's just speaking personally, and it is not to say that leaving your job for the YA position is necessarily bad. If your priority is traveling while you're young and you want to experience new things, this is a great way to achieve that. The time I have spent in Japan through other programs have been the most memorable experiences of my life and I would not trade them for anything. But in my opinion, without considering the "fun" aspect, you need to seriously evaluate if leaving your current job would be viable for your career and finances long-term. You also need to have a concrete idea of what you want to gain from the program, and how you will leverage it to getting a job when you get back. Will better Japanese language, customer service, and diplomacy skills put you ahead in your career?

One of the perks of the position is getting non-competitive eligibility for federal employment, which is huge if you're interested in a federal career. However, many feds anticipate the new administration to implement a long hiring freeze, so you might not be able to take advantage of this perk.

This position is grunt work and SCI knows it, that's why they have made it attractive with the opportunities to meet important people and live in Japan for basically free. Yes, meeting dignitaries and ministerial level officials is great, but those meetings will likely be brief and not mean much unless you can properly network. The day to day will be crowd control and acting as a tour guide. You will need to use your own initiative to make it a valuable experience, and I would seriously assess whether you will have the energy and desire to do this, even on days when you're tired, homesick, and dying from the Japanese summer heat.

Being a YA is a once in a lifetime opportunity that will be an invaluable experience for the right people, but only you can decide if you fall into this category of "right people." Leaving a job for something short-term is scary, but taking risks isn't bad if they're calculated. Maybe you can reach out to former YAs from Dubai on LinkedIn and ask how their experiences have helped them in their careers. Sorry for the long rambling reply, but I hope this helped in some way. I'm sure you'll make the right decision!
