Travel to US from UK on Indian passport

Hi,

I am working in London on ICT long Term spouse visa and need to travel to USA for business purpose.
Can I use ESTA service or there is some other category of visa for me?

You need to apply for a visa at the US embassy and meet all the requirements.

India is not part of the ESTA visa waiver programme.

Could you advice if any fast track application is available?
Us embassy website is complex to understand.

Not sure what exact category i need to apply to?
And how long does it take.

I need to travel on 9th sept

Unlikely you will get a visa so soon as you will probably also have to attend an interview. Appears to be an 8-15 day wait for an appointment.

while payment I am getting interview date as 6th Sept, do you think i ll get my passport next day?
There is not priority service to book early interview date or next day visa after interview?

I don't know. I provided the links I found on Google. I have never had to apply for a US visa but have friends who have but I don't know the process.

Okay so I got how is this possible.
You have to book first available appointment only.
Once its scheduled you will receive and option called Expedite Request.

User your creativity of words and if consular thinks its urgent he might reschedule it for you.
I just did that and now waiting.

Now I need to know how long do they take to decide this otherwise I will have to wait endlessly until my interview date.
