The completion of application forms, and supporting documentation showing the factors above are necessary for a good H & C application. Once the application package is complete and the government processing fee is collected, the application can be submitted. The application package should have a very detailed submission letter outlining all the H & C factors of the applicant and should explain why the immigration officer assessing the case should approve the application. Note that H & C cases are discretionary, that is, the immigration officer assessing the case can refuse or approve the case based on their own assessment. Therefore it is extremely important to prepare a very strong submission letter and collect persuasive supporting documentation in support of the Humanitarian and Compassionate Application.
