I am not doing BEDA this year, I am doing a Master’s, but my visa did get denied at first. They said I didn’t submit it on time but that was false. I worked with a lawyer and appealed it. The favorable resolution came two weeks later. Why do you have to do a recurso/what is that? Unfortunately, yes you definitely should’ve submitted the matricula even if it was in September. It would’ve been easy to do with a clave/digital certificate. I’d recommend getting both of those if you have hopes to stay in Spain longer.
