It is legal and so far it has been safe. You know that the rule for Day 1 CPT requires that when you join, you are associating with a graduate program otherwise you cannot get a Day 1 CPT. The Curricular Practical Training is an integral part of your degree. You cannot finish the degree without the practical training. The other thing is the employer signs the cooperative agreement with the university. The only additional suggestion I have is if you are going to do Curricular Practical Training make it as an adjunct to your profession.

I and my wife got my GC approved on June 19, 2003. We got an RFE and then our files were transferred to the local INS office in San Diego, CA. I got full support and guidance from Rajiv Khanna's office and could talk to them and reach them in all situations, I have a very pleasant experience working through Rajiv Khanna. Thanks a lot Rajivji for your help and support. Good luck
