I recently got my ilr, on long residency and i am working part time(12 hours) only because i was a international student.so, my contract was part time only.

i am planning to invite my sister (age 32) for family visit, can any one suggest what kind of document i need to prepared. her visa was already refused 2 times due to the unsatisfied bank statement of her husband when my another sister (living in london with me) try to invite her on her graduation.

thanks.........
