发现德国有一个专门针对 IT 人才的工签，只要能拿到工作录用就可以申请，对于学历没有要求。只要满足以下要求即可：

1. 最近十年中有三年 IT 相关工作经验
2. 能够通过相关的技能测试
3. 签约合同的年收入不能低于 €52,560
4. 德语要考过 B1

The type of visa you receive depends on your qualifications and your job offer in Germany. Even if you have neither any formal qualifications nor a university degree, you can still obtain a visa and work as an IT specialist in Germany. Therefore, certain prerequisites must be met.
