How should I approach this?

I just revived an email for my Master in Hochschule Darmstadt to apply for enrolment which is great but my biggest worry is how will the Visa process work for me I have enough funds for blocked account from my past year of working. I love my job and it’s great it’s work from home for a company in Spain which pays 1250 USD per month and I want to continue it along side my Masters, if anyone can clear it out for me or help with information regarding the Visa process in this case I’ll greatly appreciate it. Thanks
