In answer to your questions - you should accept the job at the nursery school, and in general you should continue to live in the United States.

It is not advisable for you, on your part, to do things to separate from your husband (if they are not connected to Shulchan Aruch [the Code of Jewish Law] - which obviously should not be compromised, for it is G‑d's will).

Regarding influencing your husband in matters of Judaism - you should find others who will do this. (This will eliminate the [cause for] resistance, as it is unusual for a husband to acknowledge that his wife directed him away from a mistake which he had lived with his entire life.)

Your efforts in this matter should be gentle and step by step.
