Hello, i have to extend my elite visa for first time. I called the Elite visa center and they scheduled an appointment and sent a document to me and to the immigration in Jomtien. I missed my appointment yesterday. 

Does someone know if i can go on Monday? Or shall i reschedule my appointment and wait other 2/3 days?

I read other posts that people went to the immigration without any appointments.

Does someone know what is the procedure?

Thank you for any help.

11 months ago, somebody posted detail of the procedure here:

 

 

If you make a new appointment with your Thailand Elite (TE) agent, you tell them your choice of date and time; don't let them make the decision. 

I did yesterday my visa extension: immigration didn't ask me any documents.

Well...
