The
core threshold for Shanghai Category B foreign work permits is clear:bachelor’s
degree or above + 2 years of relevant work experience.
Many applicants mistakenly believe that any two years of work
experience is acceptable. In fact, the official authorities have
strict, explicit standards for experience authenticity, industry
relevance, and certification format.
上海B类工签最基础、最核心的准入条件：本科及以上学历
+
2年相关工作经验。多数被退件的申请人都踩了同一个误区：认为只要凑够两年时长就能通过。实则上海官方对经验的真实性、全职属性、岗位相关性、证明格式均有硬性审核标准，并非简单累加年限即可。
Officially
Recognized Valid Experience
官方认可的有效工作经历
Only
full-time employment experience matching the post and major
background can be recognized by the system. The officially compliant
scenarios are unified as follows:
只有满足「全职属性+专业对口+岗位相关」的毕业后经历，才可被官方采信，有效经验范围固定如下：
Formal
enterprise full-time experience正规企业全职经历

Unrecognized
Invalid Experience
官方不予认可的无效经历
All
non-full-time, non-standard, irrelevant working scenarios will be
directly eliminated in the official review, which is the core cause
of B-type application rejection:
以下几类高频经历，无论年限长短，官方一律不予采信，是B类申报驳回重灾区：
Internship
& part-time during schooling在读实习/兼职
All
internships, part-time jobs and trainee experiences before graduation
are invalid and cannot be accumulated.毕业前所有实习、兼职、学徒经历，不计入有效工作年限。
Unregistered
flexible employment自由职业/个体从业
Freelance,
individual business, and working experience without formal labor
contracts are not recognized.无正规劳动合同、无备案记录的灵活就业、自主创业经历无效。
Major-post
mismatch专业岗位完全脱节
The
previous working field is completely irrelevant to the academic major
and the applied position.过往从业领域、岗位职责与所学专业、申报岗位无任何关联性。
