Colleges in Kerala

first of all you are not clear jee mains,So there is no chance

ITM Mumbai will be a better option amongst the two. XIME Kochi is new so it would be better to avoid it. ITM Mumbai has an average package of around 6lpa.

Yes, you are eligible.

First for airhostess study there is no specific college but there are many Institute for that. Like you choose frankfinn Institute,Air hostess academy.

Hello, before the F1 visa, the university will issue you the I20. Once you receive the admission offer ( here you need to pay the enrollment fee) you must show financial evidences supporting one year tuition fee and living expenses. After you have received the I 20 you need to show enough funds for the entire course duration that is tuition fee and living expenses. The amount to be shown is generally provided by the universities.
