Visa approval letter with purpose of business for travelling

Vietnam visa approval letter through air Vietnam airlines
We received our letters but they state our purpose of travel is business. However, I had chosen "tourism" when I submitted. I have tried to contact them to change this but they have not responded. Is this going to be a problem for us when we arrive at HCMC to get our visas? Both of us are US citizens. Thx

Vietnam tourist visa is max. 1 month. 3 months visa is classified as business visa. Vietnam Immigration Office classify for their managing purpose. Sure you will get no problem.
