Do I need to wait for my husband's DTV visa to apply for mine, and what are the requirements for the application?

My husband and I are in US and planning to apply for the DTV visas. I have a couple of questions and hoping this group can answer.

1. My husband works remotely and will continue to work for this company when we move. As a spouse, do I need to wait until he gets his visa in order for me to apply for mine?

2. One of the questions on the application is the address of a location we will be staying in Thailand. We have not been to Thailand yet. Do we need to have a place to live secured before applying for the visa? Could it be a hotel?

3. For the employment verification, do we need to get a letter from the company or would a paycheck stub or an offer letter when he got hired sufficient? He’s been working for this company just over a year.

Thank you in advance.
