Here is my 2 cents on the matter -
1. This is kind a new. Usually there is a clause between the client and prime vendor that the same person cannot work for client through differnt prime vendor before ceratin time expires, and they cannot turn the same employee full time before reaching certain time frame. Mine was 6 months.
Usaully consultancy makes you sign that you have to work for them for a year. But this is new. But then I think u made a mistake by signing such stupid clause in your agreement. I don't know what will happen if you break ur contract. and how far your consultancy will go to file lawsuit aganist you. But If I were you, I would read that contract again very carefully and see if there are loopholes in it.
Also talk to your employer and prime vendor if there is any clause between them as well.
Either ask help from consultancy or lie them about it. Tell them you are going back to country becuase of emergency and will not be able to continue work. Do not write in email or paper, that will lead to trail of proof if they decide to go aganist you.
2. After 1 year, they are hiring you becuase of your work, not resume. There is no proper way to verify each and every thing in the resume. When they do background check it is more for any criminal records. Also some companies verfies graduate info. Mine did. Some will even pull Credit history. But as far as resume stuff, they might call your previous supervisor and managers.
Mine was verified by Vendor. But this hsould be no issue from where I see. you can give names of two professionals as a reference.
I dont see this an issue.
3. Don't know. But in worst case scenerio u might just loose the oppourtunity. Since you r no longer allowed to work as an consultant, loosing that is not in your plate. But Employee finding about your previous resume and work experience is very minimal.
Just relaize that they are hiring you becuase they like your work.not resume.
hope this helps.....
