I am a Freelancer applying b1/b2 Visa to attend United Nations conference

[heerxyz]

Hello guys,
I have been selected to attend Youth assembly and got the invitation letter from United Nations. I am applying for b1/b2 visa.

I am single, 25 years old female and work as a freelance Digital Marketer. My income stream is smooth and I can easily afford to stay there.

The question is,

1. how do freelancers convince their ties to home country when they do not have any employment here?

2. How many of you have applied and successfully got it?

3. Any tips to convince them that I'll return back to Pakistan?

1 & 2. Only you know your exact situation. Therefore, you will have to explain how you can do that job there and not in the US.
3. Yes.
