There are many visa applicants who are working as an unregistered freelancer (photographer, construction contractor, fashion designer, journalist etc ). Some of these freelancers make really handsome monthly income and don't really need to work as a full time employee. Most of them receive variable amount of payments (cash, cheques, demand drafts etc) When it comes to filling a visa application form (USA, UK, Schengen etc), there is always an employment section in all visa form, eg for Schengen visa employment form :
This is a very important factor to make an application really strong.
1 Unregistered freelancers can just simply write their profession? what documents to produce along with the application?
2 Bank statements with variable methods of payments could convince the visa officer that these are all legitimate payments?
