What are the steps I need to take after arriving in Thailand with my OA visa?

Hello to everyone here 😊🙏

I got my OA visa very easily and smoothly without any hustle and drama.

Next week I am coming to Thailand. Could someone explain to me step by step what will be the next steps ?

I am providing you with some information:

-I will stay in my girlfriend's house but we will travel a lot and stay in different places in Thailand for short or sometimes long time ( between 3 days and 2 months).

- I want to open a Bank account or two.

- i want to do a motorcycle license

and

I want to get a driving license for car ( European driving license and international driving license for car are there)

Thank you in advance for any good advice and healthy suggestions

🙏😊🙏
