if ur prometric n dataflow is over,then the hospital offering u the job will take care of the rest,like evaluation,visa n license..evaluation takes some time.its a mutual understanding that u accepted their offer..how many years of experience do u have..before commiting to them,do a survey and see which hospital gives a good offer..also check the other benefits they offer..dont just hurry n fall in some trap..if u hv nurse friends ,check with them..
good luck
