job as a teacher at an international school

Welcome to the board. That is a super hard question for anyone to answer without a lot more information. If you want to know if the school is solid, it is. As with many of the schools here now, I would imagine enrollment is down this year since the storms took a lot of people off island. Especially those with school age children. But I think we will see an uptick in enrollment for the start of next school year as long as we don't have another bad storm prior to the start of school.

Without knowing how much money you will be making, and what you consider a comfortable lifestyle, hard to say much there. You can look around on this forum in older posts to get an idea of what things are like here. You can also look for classifieds for places to rent to get an idea of how much things cost. On St. John, there is a shortage of long term rentals available. Not sure how it is on St. Thomas, others can chime in.

Thanks for your advice

That school has a very strong knit community and I'm sure they will bend over backwards to make you feel welcome and will help you find comfortable, affordable accommodations. You won't feel alone.

The VI celebrates PR Friendship Day every year instead of Colombus Day because Columbus didn't discover anything. The holiday is more popular on St Croix than St Thomas, but it's good to know the islands celebrate the connection.

A Puerto Rican chef recently opened a restaurant in a popular condo/vacation rental complex not too far from the school and they have a Puerto Rican night every Thursday which may include a pig roast.

There used to be a very popular Lechon truck before the storm but I haven't noticed if he's reopened. He's been here forever.

You'll have plenty of opportunities to visit PR and as more flights return prices should become competitive again. I was paying around $120 rt I think before the storm.

The PR "shopping ferries" were very popular before the storm. People would go over to buy bulky items at WalMart, Best Buy, etc and bring them back on the ferry. I think RT fare to Fajardo was $125 and you were able to stay for maybe 2 days or more. Very popular for Thanksgiving Day departure.

I certainly think you will be welcomed by the faculty and parents there, it is an excellent school with a long established reputation..
Network with the school community and you will likely find an affordable apartment, bring as much money as you can, you will probably have to buy a car.
Your salary won't have you living in luxury but you won't need winter clothes and St Thomas will satisfy the Caribbean need you are feeling.
It is a very good opportunity with positive upside.

Also, the VI recovery is moving along faster than PR recovery, because properties not as remote. Recent news says PR power outage 2nd longest in history. People from VI who were in PR during storm and had to stay for a while felt as though VI response was quicker to provide water and food. VI may have more influential "friends" right now than PR so may get more resources per capita than VI for now.

Thanks
