Hi I hope someone could help me!

I have some concerns regarding some of the information I have found online, stating there is a limit of travelling into Thailand 2 times per calendar year, I also saw something saying about a 6 month period too. I have applied for a student visa but the school have said I have to do a border run as they are full and I cannot start until I return..

I entered Thailand on 17th October 2023

I then departed thailand on 13th December 2023

I returned to Thailand 27th December 2023

I then departed Thailand on 18th January 2024

I then entered Thailand on 8th June 2024 - 6 months after leaving

Can you just confirm that I won’t have an issue when doing the border run without a border run company and if so why would it be different with a border run company? Thank you 🙏🏼

I have been issued with a new passport. My Question is : on my old passport i traveled out of Thailand to Cambodia and came back on a tourist visa. How many times can I do this and get 30 days (travelling by land) thanks
