Will the customer problem be the same in the US?
Validating the customer problem and the solution happened a long time ago for you and your company. You identified a real problem in your home market. You built a solution. Your target customer was and is willing to pay for it and you have been growing ever since. It is easy to assume that this will work the same way when you come to the US. This is a dangerous assumption.
Heavily regulated markets like healthcare, financial services and education are just examples of what are likely to have significant differences that will require major adjustments to business models.
What do you recommend?
A saner approach when entering the market is to assume that the target customer, the customer problem and the required solution will vary from what you have seen in your home country. Revalidating the customer problem and the solution fit is an important step to take before you go all-in on sales and marketing.
