Sorry to have to post something like this, but I have been receiving horror story after horror story the past few weeks, and there is absolutely no reason that you have to put up with any of those lies.
From DHEL28's agency placing 9 people in one apt without heat in NYC in the winter, and only one bathroom, they were told that accommodations were provided. And not even a bed, they had to buy that for themselves. To another agency incorrectly filling out documents so that the nurse got denied, then telling the nurse that the agency was going to pay for an attorney to go to Washington DC to correct things. But one year later they have not been resubmitted with the corrections, and number two, the immigration centers are not in Washington D.C. And this nurse was also told that the agency would know twenty seconds after arriving in the US that he was here. Impossible. And another that had a $25,000 cancellation policy but told that if she tried to leave, it would cost her about $100,000.
If you are having issues with your agency being untruthful and taking advantage of you, please contact the Embassy for your country here in the US, as well as the US Embassy in your home country where you had your interview.
Once you have arrived in the US, you cannot be deported. Do not let an agency threaten you with this. The green card gives you permanent residency.
