Hello Aspirant,

Yes definitely you can go for MS in abroad even if you complete Integrated M.Tech from India because as far as my information there is no such rule of any Institution in abroad which does not allow the candidates to pursue MS in their institution for having integrated M.Tech degree.  As you are seeking admission in abroad so you have to appear for some tests as well like TOEFL, IELTS and one or two others whatever required by the foreign institution but for most of the institutions TOEFL and IELTS are compulsory exams for admission in abroad.

I hope this information helps you.

Good Luck!!
