on WP Tier 2, how to invite sister for vacation from India?

[abhaykulkarni16]

Hi,

I find so much info on this forum that I decided to signup and ask this specific question, as I find that the answers vary from case to case.

Well, here's my my case -
I am in UK on Tier 2, arrived a month ago.
Before summer ends, I want to invite my sister from India.
Since I arrived only a month ago, I don't have salary slips here, but have a sponsor/PBS mentioning my salary certificate.
I am living on sharing and would not do a tenancy in near future. But I could spare her a room, which is easy, or worst case a serviced apartment/hotel.
About my sister, she's done her graduation exams and awaiting results. So is free for next 2 months.

I am aware of the things required for Invitation, and I would actually be able to take complete care of everything related to her stay, food, etc.. but can someone guide me if this is actually possible this way?
or else, i would arrange a all expenses paid trip. actually, which is better?
