I just downloaded the new SSDT for Visual Studio 2017 (15.3.0 preview) and although I selected Integration Services during installation it isn't showing in the New Project window.

Solution
You probably already had Visual Studio 2017 installed and added the Analysis Services and Reporting Services project types via Extensions and Updates.
1) Remove projects
Go to Extensions and Updates and remove both the Analysis Services and Reporting Services projects.
 |
| Remove SSAS and SSRS projects |
After that close Visual Studio and let the VSIX installer, uninstall both projects.
 |
| VSIX (un)installer |
2) Uninstall SSDT and Install SSDT
Then first uninstall SSDT completely. And then install SSDT (Repair didn't work).
 |
| Uninstall and install SSDT |
3) Create new SSIS Project
Now open Visual Studio and create a new SSIS project.
