No. It will not create any problem while document verification since you have got your Transfer Certificate (TC) as well as Course Completion Certificate. Generally people will have some complications like non-payment of fee, ..etc., due to which those final certificates may be stopped giving you. As you have taken admission in 2018 already, it means you have got some certified certificates from a recognized college and hence you are been promoted to next level of course.
As you have got them already by now, it'll not create any issue in getting government job. While document verification the following things will be seen keenly. If you can follow the things properly, I can assure you that you will be getting job provided that you have scored more than required cutoff marks.
During document verification in Government recruitment's following steps are taken in general:-
1) Those who have been shortlisted till 2nd or 3rd round of the recruitment process, will be called for Document Verification. Sometimes, the final round like Skill Test/ Document Verification will be done on the same day.
2) You will have to bring call letter for Interview, 10th Marks list, 12th Class Marks list, Graduation marks list, TC, Caste Certificate (If applicable in case of reserved category), Residence Certificate (sometimes), Proof of Identity, Color Photographs, all the other required documents..etc.,
3) Verification authorities will be checking whether they are true or not and verify the candidature and then generally original required documents will be taken (Dossiers) and they will be sent to your corresponding Employer once it is known that you got selected.
4) You can then go and join your Employer within the prescribed time and then you will be taking your originals back by signing "Received Copies in Original" on your Office letter.
So, this way verification will be done and no where they will check during which year you have collected your documents and all. They will be looking only whether you have got the required/ necessary documents with you or not. Hope my suggestions would be helpful to you.
