Income tax requested for DTV application - not having one since being a nomad:

Got requested - Financial evidence: an amount of no less than 500,000 THB, (e.g., bank statements for the last three months, sponsor letter) (already provided)

+ Provide the salary slips/income for the past 6 months, please highlight them in your transaction records, and provide your income tax last 2 years.

I have 2 questions:

1. Since, I've been moving around multiple countries (less than 6months each country) - It wasn't required by any of these countries to pay income taxes - what should I attach as income tax for the last 2 years?

2. I attached the bank statements for 3 months with over 500.000vnd.

Now that I will have to attach the payslips for the past 6 months, should I just highlight them in that 3 months bank statement - or should I attach another 6 months transaction record which I haven't got?

I have a question regarding the DTV application under the workcation category.

I’ve been living in Thailand for the past 6 years on a Non-B visa while working full-time, but my visa will be canceled on January 31st. Then, I’m planning to apply for DTV from Ho Chi Minh in early Feb.

I plan to provide employment documents from two companies that I’ve worked with intermittently. However, since these are my friend’s companies and I haven’t received a formal salary, I’m wondering if it’s okay to create new employment contracts starting February 1st to show it as a new opportunity?

For proof of funds and bank statements etc., I'm planning to provide salary slips from my full-time job for the past 6 months.

I hope that makes sense! Any suggestions would be highly appreciated. Thanks in advance!

Is bank statement with 500k THB enough? Or are salary slips + bank statement with 500k mandatory?
