This appears to be due to some of your option settings. I don't use
Go; I just tried some experiments starting from:

$ vim -N -u NORC --cmd 'filetype indent plugin on' thing.go

Typing

import (

and hitting Enter indents the new line by a 'shiftwidth'. By
default, this is a single tab. This behavior is affected by at
least:

'shiftwidth'
'tabstop'
'expandtab'

If you are seeing several tab characters at the start of that new
line, it would be because your 'shiftwidth' setting is some multiple
of your 'tabstop' setting.

There are a number of ways to change that behavior to what you want.
I would recommend creating a file named

~/.vim/after/ftplugin/go.vim

and putting there the option values you want, set using "setlocal",
not "set", so that they will apply to only Go files.

Take a look at:

:help 25.3
:help 'shiftwidth'
:help 'tabstop'
:help 'expandtab'
