Wissen Technologies Offer Letter

Hi, i am getting an offer from Wissen. I have 4.5 years of work experience as a developer. Right now I am staying in Jaipur. I would have to move to Bangalore to join Wissen. I am so scared, when I was doing my current job, I really wanted to shift to Bangalore but I am really scared now. I do also have an offer from Gurgaon but Wissen has a good name.

Please any suggestions or advise would be really helpful.
