New grad program dilemma

I've never had a problem getting time off for previous commitments when accepting a new job. You probably won't have enough vacation time saved up to take a month off by then (unless you already have the time saved up from your current job, and it can be carried over into the new one), so you wouldn't be getting paid for the time you're gone- but they may allow you this leave of absence since it was already planned before you took the job. Since it's a new grad program, depending on the duration of your training, they may not even be relying on you for schedule coverage by then.

I agree with you about using the "family emergency" excuse being unethical. I don't think it's good practice to start off on the wrong foot by being dishonest. I believe in dealing with others in good faith. If being honest costs you this opportunity, then the sooner you know the better, so you can figure out what to do. And, you'll be able to sleep better at night knowing that you conducted yourself with integrity.

If it's already been ten years, a little longer shouldn't make too big of a difference. If you're in a tight market, I think you should keep the job. The "family emergency" excuse doesn't seem likely to work, anyway ....especially for such a long length of time.

I get it - I am an immigrant with not much family in the US.

But think about it a bit.

The longer you wait to get your first nursing job or start the harder it will be to get something. The market for new graduates is rough. The new graduate program will give you the first work experience you need plus hopefully will lead to a position that is long lasting so you can work at least 1 - 2 y with your first job. After that it is much easier to get another position, take time off and so on.

It may be better to just go ahead and do the program plus work for a bit - then review if you can take time off. Not working or stopping after only a few months can change your future path.

I am not saying you should not go but to think about it carefully.

What if you stay and work and let your mother and other family member go?

Just a thought. Hospitals in my part of the country will only hire new grads via their nurse residency programs - and these have very rigid start dates in January & June. If you can't attend, you don't get hired. I hope that's not the case in OP's situation.
