What are the options for my friend facing a visa denial in Spain, and will she need an exit ticket for entry into Thailand?

Hello, my friend applied back home in Spain for a 6 months visa and a 3 month visa this summer. Both have been declined. She has been asked to have an interview in person, which for she is waiting to hear the day and time. The reason for denying her application has not been shared.

First question? In the mid time, what are her options?

What about getting a new passport and getting a visa on arrival in Bangkok? This would preserve her flights to Bangkok and Chiang as they are. Once there, she can apply for a volunteer or martial arts visa and travel to Lao or any other place to process this.

Second question, will she need to show a ticket out of Thailand on arrival?

Thanks for the guidance.
