I am currently in UK working for company A from India who processed my H1 , i have gone through the lottery and got my EAC file number. But i dont have he i797 which is with my current employer who processed my H1. Now i need that doc from USICS. I have got an offer at US and the new company is ready to transfer my H1 ,so that i can start my job at US, am currently in UK, will the USICS respond to me quickly if i write a letter asking for the copies of my i797 or the other docs submitted ? if so what should i do to get the response quick?
