截至目前，全球已有47个国家推出数字游民签证计划，其中葡萄牙的D7签证最受欢迎，允许远程工作者在该国居住一年并可续签。统计数据显示，2023年中国申请数字游民签证的人数较2022年增长300%，主要群体为软件工程师、设计师、自媒体创作者等数字工作者。

这一趋势催生了新的服务行业。 specialized agencies now offer "digital nomad package services" including visa application, tax planning, and cross-border insurance. Some co-working space chains have developed global membership programs that allow digital nomads to use their spaces in multiple countries.

However, challenges remain. Cross-border taxation is complex - some countries tax based on residence, others based on source of income. Social security coordination is another issue, as many digital nomads fall through the cracks of national social security systems. Experts suggest establishing an international framework to protect the rights of digital workers.
