Hi,
Germany is very competitive and you must have excellent academic grades. Compared to Germany, Ireland would be easier if you are an average student. As an international student you must submit a valid IELTS score. For further requirements you must visit the universities. Kindly, check:

Dear Jini,
The computer science industry particularly engineering, gaming and animation are huge industries in Ireland.

Dear Ramya,
I believe that BCA degree which is a 3 year degree course, will not be easily accepted in US. Ireland is comparatively easier. Eligibility differs with universities so please check the university websites.

You can go for online courses on Coursea or EDX. It can also add extra credits to your college application.

You can't get admission with pure B.Com. You have to do IELTS and TOFEL, if you want to go abroad.

Well both the countries offers more or less the same schemes. 12 to 6 months in Ireland depending, if you hold a level 8 or 7 degree. If in Switzerland, you have 6 months to look for a job and you cannot extend the 6 months work permit.
I will favor Ireland because you may have allowed to extend your permit, if you obtain permission to remain in the country by pursuing further study, permission through another scheme or obtain a green card.
You should always check the immigration websites and contact them. The universities also have separate international student's offices, please check with them and make a comparative study.

Go for UK, Germany, Canada, USA or Australia for IT.

You need 6.5 bands in IELTS for a good college.
