marriage or hospital sponsor

There are no green cards available for you right now with hospital petitioning, nothing past the I-140 can be submitted. And once your OPT is completed, then you will have to leave the US within 60 days if things do not open up by then, and we do not expect them to for the AOS processing.

It is entirely up to the officials at immigration as to what they will accept from you and that includes proof that there has been a relationship in place for sometime, not just being used to be able to stay in the US. They make the final decision on this.

People get married because that is something that they truly want to do, not as an excuse to be able to remain in the US. You are looking at several years before having a chance at a green card thru an employer, and that can be longer depending on your country of birth.

Right now, even if a hospital sends in all of the documents, there still is only the I-140 that can be submitted once you pass the NCLEX-RN exam. We do not expect anything to open up for several years for the AOS petitioning, so it means that after the one year of the OPT, you will only have 60 days to remain in the US.

Each case is looked at on its own merit, and the final decision is up to the immigration officer that reviews your case to start with.

You will have one year of work under the OPT, and if you are planning to marry, then I would not wait, or you may find yourself having to leave the US; always a chance of that.

You will not be able to work past that one year unless you do something else such as continue on with school to maintain your student visa, that is the point that I am trying to make to you.
