Answer 1: Employees cannot legally pay for green card expenses, H-1B fees, or premium processing associated with PERM. For the green card process, the employer must cover all costs. In the case of the I-140 stage, the employer should pay, especially if the employee is on H-1B. However, for the I-485 stage, the employee can pay.
Regarding H-1B, the employer should generally cover all expenses, except for premium processing. If premium processing is for the employee's benefit and the employer opts not to pay, the employee can choose to cover the cost. If premium processing is for the employer's convenience, the employer must pay.
In summary:
Green Card (PERM): Employer must pay; employee cannot.
I-140 stage: Employer should pay, especially for H-1B holders.
I-485 stage: Employee can pay.
H-1B expenses: Employer should pay, except for premium processing.
Premium processing: Employee can pay if for their benefit; otherwise, employer must pay.
Answer 2: Additionally, an employee with an old H-1B stamp from a previous employer can use it for a different employer. There's no need for new visa stamping if there's a new approval notice. Traveling on the old stamp with the new approval is permissible.
My wife and I got the I-485 approval email notice in June 2007. We filed the I-485 in April 2007. The LC was done by another law firm and I switched to Rajiv and filled the I-140 and I-485. The I-140 was approved in one week under Premium Processing and I-485 was approved in less than 3 months. I told our company HR to switch to Rajiv S. Khanna and we are processing our employee’s H1B and GC through Rajiv. During the GC process, our company was sold and Rajiv and Mathew helped to resolve this issue, rather than starting the GC process from scratch. Mostly I dealt with Prerna Mehta and Mathew Chacko. Both provide me excellent help and support during the process. I dealt with Rita Dhakal for a short period of time and she helped me in great deal. Mathew called me on my cell phone to answer my questions, and he was polite, fast and correct. Also, I praise Prerna for checking my documents and forms thoroughly (I did not get any RFE) and providing correction/feed back immediately. I found the Rajiv’s immigration forum would be one of the best places for gaining more knowledge, and I would recommend every one to read and learn more.
