I am from India. I have been invited to a conference in AI to be held in Australia this year. I want my wife to accompany me during the trip, since we wish to tour Australia as well during the same period. (We have been married for only 5 months and this will be our first long trip together.)
As I understand, I need to apply for a business visitor visa, while my wife needs to apply for a tourist visitor visa. Should we apply in a single application or separately? Moreover, I am a scientist, while my wife is not working currently. My trip is completely sponsored by my company, whereas I will be paying for my wife's trip. What will be the best way to present my case to the visa officer?
