How to get an assistant system administrator job in Germany as a non-EU citizen?

Hi everyone,

I'm currently working as an assistant system administrator in my home country (outside the EU), and I would like to move to Germany through a Blue Card or visa sponsorship. I have experience with:

• Windows Server (basic administration)
• Active Directory, DNS, DHCP
• Group Policy configuration (like blocking apps, setting static IPs, printer sharing)
• Basic networking and desktop support

I have started learning German. My main goal is to grow my knowledge, earn a stable income, and build an IT career in Germany.

I'm looking for advice from people who have made a similar move or know how the process works. Some questions:

• What’s the best way to apply for junior or assistant sysadmin jobs from abroad?
• Are there companies or agencies that support visa sponsorship for entry-level IT roles?
• How important is a degree or certification (I have practical experience)?
• Is it possible to get hired without visiting Germany first?
• Any tips for making my resume or cover letter stand out?

If you've successfully moved to Germany as an IT specialist (especially without a degree), I’d love to hear your story or any resources you recommend.

Thanks in advance
