can anyone reply please?

Always self sponsor is the best choice in B visa category.

Since you both are working, you can sponsor the trip together.

If you both are sponsoring, you may tell your combined income per month.

By the way, when your sister visited you last time?

if she visited you very recently, then it is not a good idea to apply immediately.

This is my opinion, not a legal advice.

She visited 5 years back, on my marriage.

Thanks 'Ideal sol', can someone please answer on other points?

plan for some ocation or vacation as purpose of visit like...

House warming, marriage of some close relative,
Christmas or new year celebrations etc.

Prepare a well planned itinerary like...

How many days you want to be there and what are all the places and people you are going to visit.

Take a leave letter/ noc from your employer (both)

Take a copy of your sister's passport.

Generally they ask for

* purpose of visit
* income
* family ties (father, mother or any dependents)
* past travel history (abroad)
* who is sponsoring the trip etc.

As per me your chances are good.

Prepare well and give straight and brief answers.
Don't be nervous.

All the best.
