Some embassies require the business registration of the company you work for. I had to give it applying as freelancer.It is the legal registration of your company, your HR Dept should know. You can even probably look it up online
The one month membership approval was easy to get last year. Now 6mths minimum plus demonstrate your long term need for the DTV to avoid rejection or given a 6 month METV.
My PT online income was a bit less than that. I also emailed them telling the income and they said it was fine to apply as did London, Vietnam, Manilla, no minimum income etc. When I applied, I got the miserable lady others complained about. She kept saying " not enough money" even though I showed her the email. She was fine with adding investment income.
