TanviWatts:
Responding to your questions:
1) I'm currently not working but for lor from the manager/supervisor, does my manager need to have the same company ID I was working at because they also don't work there and have a different email from another company. Can I add that or does it need to be from someone from the same company with the same official email.
A: It's fine to have a separate email address. One of the first questions that is asked in these LORs is "how do you know this candidate" so as long as that person adequately explains the relationship, you should be fine independent of the communication method. You also have to indicate the nature of your relationship to your recommender in your own application, so you have double coverage.
2) After leaving the job I started my business for which the income proof would be hard to present, how do I go about that or do I skip mentioning it
A: Do you need that information in this part in the process? I believe an approximation should be fine. For when you need to validate it, you can probably show a tax return or however you would prove your income to the government for official purposes.
Hope that helps,
