You are personally fully responsible for the content of the application you submit. If you were persuaded to accept a service from one of the many persons assembled around the Embassy, we request you to clarify the matter directly with these persons.
Everyone can complete the visa application form himself/herself, and does not have „better chances“, if he/she receives help from other persons for this.
Please make all statements according to the best of your knowledge and according to the truth.
Do not let anyone tell you, that a professionally completed application will lead to a visa – nobody can promise you the issuance of a visa! Everyone can answer the questions in the application himself/herself.
