How can I gather additional information from the candidates when they apply for the job(s) advertised by me?
You can do this by creating a questionnaire and attaching it to your job(s). For example, if you want to check if the candidate has an H1B visa or not, you can add this question to your questionnaire. Once you assign this questionnaire to the desired job, the candidate is prompted to answer this as soon as he applies to that job. You can also mark the question as mandatory besides having different formats of questions like: open ended; multiple choice questions. You can also save this questionnaire for re-use.
