We went to Houston with a just turned 2 yr old. DH had already done a couple of 1 month placements there to see if it would work for employer and employee.
From my experience (which was a good while ago now):
The pros:
Houston is a big vibrant city, with lots going on. DH’s company had a good relocation system both in terms of the practicalities of arriving, finding somewhere to live, getting stuff shipped over, buying cars, finding white goods, sorting insurance etc, and in having a buddy system for trailing spouses, and I met quite a few people this way.
It’s a major hub and easy to travel to places for short breaks - we were only there for a year but went to California a couple of times and travelled all across Texas.
There’s a big ex pat community and you can get involved through this.
We had a lot of visitors from the UK - it seemed like someone was coming over every few weeks.
Our lovely US neighbours helped me get DC into an amazing pre school. It was run by the Southern Baptists so fine for youngsters (church is a big thing). My primary school teacher MIL was blown away by the facilities.
The cons:
It’s expensive - housing costs, utilities, insurance, groceries, eating out etc. We had a lowish housing allowance and kept our UK house on and rented it out, so the UK rent kept our house ticking over and we were essentially spending the mortgage amount on the rental. We had an older single storey house so cheaper to rent and cool, but in a good subdivision.
We had an upfront cash sum to help with initial costs, which made it a really good deal for a year. We made sure we had relocation costs back to the UK included in the package, which was just as well as DH ended up quitting to get a big step up career wise back in the UK with a different company.
Health insurance is very expensive - even our company scheme (which apparently was excellent) was a big chunk of salary each month. As we were planning for a 2nd DC we had to have the top level family cover.
If your DH is on an intracompany transfer, you will be completely reliant on him - he will get a social security number and you will get a tax identification number (or at least that’s how it worked when I was there). I couldn’t get a phone contract in my name as I needed a SS number.
Houston is hot and humid in the summer, although you will get used to it (more or less!). Be aware that there is wildlife that you don’t get in the UK, there are snakes and spiders that you need to avoid.
US holiday entitlement is very limited, so that might be something to negotiate on. I think we negotiated extra days plus carrying over our unused UK days.
You do need to recognise that many Texans are into the gun culture. We always assumed that everyone was armed and ensured we were super careful when driving, and it’s something you need to consider when kids are on play dates (are weapons secured away from children).
There’s no way I’d want to take a large elderly dog to Houston either - friends in Houston had left their dogs with relatives back home.
DH had worked in the ME, and found Houston a bigger culture shock than Saudi. Don’t underestimate how different it can be.
In the end, we couldn’t make the numbers add up past that first year and were being pressured to start applying for a green card, so took the opportunity of a change of job / company and a return to the UK (albeit to a completely different area).
It was a great opportunity for a year, and I’m glad we did it, but we were both keen to do it and we were both a bit naive too. It was good timing for me - DC was young enough for it to be easy and I was happy to leave my job and put my career on hold.
From your posts it sounds like you really don’t want to do it. A good company would fly you all out for a week to have a recce, and you definitely need to know the exact package before you agree.
You both have to want to do it, go in with your eyes open and a Plan B if it doesn’t work out or one of you wants to come home.
