need advice

[adie]

I'm applying for visitor visa to attend a medical conference and also want to visit my brother.
I'm a medical officer(MBBS). The website of this conference autogenerated an invitation letter when i filled the data.
I got invitation letter like that. I paid 900$ for the conference.
is there any chances to get the visa? I've been rejected once a year ago.
what type of docs i need?
Please help me asap.

You can consider a B1 (https://www.immihelp.com/usa-busines...-requirements/) or a B1/B2 visa (https://www.immihelp.com/usa-non-immigrant-visas/)

To get these types of visas you need to show strong social, economic or professional ties to your home country.

In your case you can make sure that you a get a signed invitation letter with contact details of the person/association inviting you.
