L是旅游簽證，旅游簽證是沒有工作權(quán)限的。
在中國唯一可以工作的簽證就是工作簽證。
嚴(yán)格來講自己做個體也是需要辦理工簽的?？梢哉覀€公司單位掛靠下，給你老婆提供材料，然后辦理工簽，拿到工簽后，自己再做生意就可以了。
工簽時間也長一簽一年，到期在中國直接延期。所以辦理下來后還是比較方便的。

關(guān)于簽證變更問題

你要工作簽證正規(guī)的途徑是先要有公司聘用你，申報材料：擬聘外國人的申請報告；擬聘外國人聘用意向、原因；擬聘外國人的履歷證明；擬聘外國人的健康狀況（當(dāng)年）證明；擬聘外國人的學(xué)歷或?qū)I(yè)資格證明；用人單位的批準(zhǔn)證書和營業(yè)執(zhí)照（副本），法律、法規(guī)規(guī)定的其它文件。
你應(yīng)該還要回趟韓國，然后在中國駐韓國領(lǐng)事館申請來中國的工作簽證。
另一種方法：你可以找個中介公司咨詢一下！

下面是南京的一些標(biāo)準(zhǔn)，你可以參考一下
