NIE number application takes a long time
If you need a NIE number, be prepared for a long waiting process. In Alicante and most other places, NIE application is by appointment only. The current waiting time is as much as 3 months! The consulate is London is by far a quicker option.
NIE number, when do you need it?
When you want to purchase a house in Spain, you need a NIE number. Without NIE number the title deed can not be signed. Fortunately, no NIE number is required to sign the previous sales contract and reservation payment. Also, opening a bank account merely based on your passport should be possible. So, you can take the first steps to become owner of a Spanish home, also without NIE number.
