Some questions about Interac before I start working with them

Hi friends of Reddit!

I just recently accepted a job offer from Interac and will be placed in the Kanto North branch with a scheduled departure date of March 2026. While I'm really excited to move to Japan, I'm also super nervous, especially about the visa application process and getting approved for a CoE. I'm in a pretty unique situation. Although I am American and was educated in English, I spent the first several years of my life going to school abroad. I also did my first two years of high school online. I got letters from my old schools confirming that I received an education in English, and I already mailed them to Interac's North American office, but I still can't help but feel anxious about everything. So, here are my questions:

1. How long does it take to get my CoE? After that, how long does it take to get my visa?

2. When will I know where I'll be placed? Will it be closer to my departure date?

3. What if I don't get my CoE or my visa by March? Would my offer be rescinded? Would my start date be pushed forward?

4. I know Interac can help find me an apartment, but how long after I arrive in Japan do I move in to it? How long would I have to stay in a hotel?

5. If you are currently working in the Kanto North branch, how has your experience been?

6. Any general advice you would give me as an ALT?

Before anyone comments anything negative, I'm fully aware of the issues with Interac and dispatch companies in general. This isn't a job that I am planning on having long-term; I'm just going to be there for a couple of years at most. The pay definitely isn't the greatest, but I can manage, plus I've already got a decent amount in savings. Any advice would be appreciated. Thanks in advance!
