Are you interested in what she does? If the interest is one way rather than mutual, it's a challenge. Not necessarily a deal-breaker, but if you're lonely in your main relationship and you're not comfortable just keeping different parts of your life in different boxes, that will become more of a burden with time because you will keep feeling ignored.
Some of this feeling may overlap with being an immigrant. Consider going home for a week or two (call it a business trip if you want) to see how that shapes your emotional perspective.
